Night Angels Chronicles, 1

“Be careful who you love, it just might kill you.” 

When Sera’s father is killed in a horrific accident, all he leaves behind is a mysterious key. Sera places the key on a chain around her neck and vows to avenge her father. Strange characters arrive in town including the otherworldly Night Angels, who claim to be sent for her protection. 

Sera falls hard for one of them—exotic, arrogant Peter. But what if his promise of love is only a ruse to gain access to the key? As Sera’s connection to the key grows, so do her supernatural powers. Guided by clues left by her father, Sera searches for the hidden chamber beneath the city, hoping to save what lies within before the sinister mayor and his deadly followers drown humanity in a bloodbath.

Before my dad’s death and the move to Cliffside, I had known only lies. I hadn’t seen the truth about myself, my family, or my friends. But here on the ground, covered in blood and dirt, and most likely dying, I knew I didn’t want to go back there. I wanted to stay with the truth. The truth hurt like hell, but it was better than being numbed by ignorance.

“No.” I think I said it out loud, but it sounded more like a gurgle. I tried harder. “Never give you the key.” I gasped. “Never.”

He hissed in anger. “Then I will turn you into undead.”


I knew he was bluffing. If he turned me into one of them, he would never get the key. I had to willingly give it to him, with a rational mind, and those undead were anything but rational.

Gore howled like he had on the plateau, and the nail raked across my face, penetrating deep into my skin. He reached down and licked the blood with his long snake tongue, a poison so painful seeping into my flesh that I almost passed out again.  

When he spoke next, his tone was venomous, each syllable biting as if they were his teeth. “Clever girl, I will do something better. I will turn your brother into undead. Think on that.”

I made a feeble sound of terror, struggling to get up and unable to move.

He laughed. “You will give it to me now. Or else your brother will end up like this.” He grabbed one of the undead and pulled the grotesque, dead-eyed face down next to mine. Then, he tossed it away like a stick.

This was the end, then. Gore had won. I had to at least try to save my brother, even if Gore's promises were lies. With unbearable effort, I reached up and tried to undo the chain. I couldn’t. I tried to pull it up over my head but somehow, it became tangled in my torn clothes. I was too weak and the problem of removing the key from around my neck overwhelmingly impossible.

“Come, little bitch, quickly.” Gore’s fingers dangled in front of my face, as if itching to undo the chain for me. But he was powerless to do so.

A growing uneasiness rippled through the undead standing in a circle behind him. Low moans rose from cavernous mouths. Any second now, surely Gore would unleash the hoard upon my brother to devour him. Why, oh why, couldn’t I undo the chain?

I grabbed the key and pulled with all my remaining strength, whispering, “I want this. I want to give him the key. I do.”

Sera is a spoiled girl who walks amongst the popular crowd at school. She and her friends are thinking about which dresses to wear and the latest must-have shoes. All of this changes when Sera's father dies mysteriously. It turns out that he's been taking out all of the money that was in their accounts and now there's nothing left. Sera, her brother Salem and her mother have to get used to a more humble life and have to move into a trailer. Sera's mother is not really supporting her children and only thinks about herself. Salem is involved with a gang and becomes more and more distant every day. Will they be able to get through their grief and become a family once more? All that Sera's father left was a black box with a key inside. Sera wears this key around her neck and feels very protective about it. Sera has doubts about her father's death being an accident and she's been having terrible meetings at night with horrible creatures. Will she be able to keep herself safe? Key of Mystery is a gripping story. I liked Sera from the start. She has so much to deal with, but she takes everything with her head held high. Sera is a smart girl and she's incredibly loyal towards the people around her. Sera knows she's in danger and still puts others before herself all the time. I loved to read about her journey and the way adjusts to her new life. Will Sera find out which door will be opened by the key she holds so close? Key of Mystery is an amazing story about a young girl who has become a very important person to the supernatural world. Sera's once so ordinary world is now filled with vampires, nasty smelling zombies and mysteries. I love the idea of a secret chamber that can only be opened by an enigmatic key. K.H. Mezek doesn't give away everything at once, she skillfully divides her suspense, and I liked to follow this road together with Sera. Key of Mystery ends with a spectacular cliffhanger and I absolutely can't wait to read the next book in this series.

Addictive YA Fiction Adults Can Enjoy Too
Written by JH on 3rd Feb 2018

This is an addictive fantasy series that has ties to historical figures, vampires, and politics in L.A. This is the first book in the series, and it starts off in present day with grounded, human drama that we can all relate to - the death of a loved one, finding out friends aren't as loyal as you thought they were, family drama, school drama, & new relationships. We see this all through the eyes of a young woman/teenage girl who is just beginning to truly know herself outside of her superficial social life. All that quickly mixes in with an unfolding mystery surrounding a key that may be connected to the shady death of a loved one who I mentioned earlier as well as an introduction to a secret, supernatural world also connected to the key. I particularly liked that the characters in Key of Mystery were well developed & interesting. By the end of the book, I was sucked in. And the cliff hanger at the end had me in a hurry to get to Book of Angels (book 2 in the series)!

Sera thinks her dad isn't dead like she's been told, she's convinced he is still alive and she's looking for him. Something sinister is going on in her city and her archenemy Fabian Gore is involved in it somehow. However circumstances force her to work together with the man she despises. Sera is worried about her mother, who's under Fabian Gore's spell. Why do people like him so much and what is he actually doing? Sera used to be able to rely on Night Angel Peter, but their relationship is complicated. She's part of a powerful group now, but they can't help her with her quest. She needs to find her dad by herself. With a little assistance from her human friend Jimmy she finds a way into one of Fabian Gore's suspicious properties. Will she find the clues she needs there? Is there a chance Sera and her dad will be reunited? Cave of Secrets is another fabulous story about Sera and the mysteries she needs to uncover. Sera is a strong girl with a good heart. She's fierce, resilient, smart and impulsive. I like her fiery nature and her brave character. She doesn't stay away from dangerous situations if it means she can rescue someone she loves or gather more information about the mission her father has given her. The Third Night Angels story intrigued me just as much as the first two and I read the story in one sitting. K.H. Mezek's writing has an easy flow. She combines gripping fantasy with important life lessons about self control, drugs and depending on the right people. I love the subtile way she does that. Sera has an important mission that fascinated me from the beginning. It was interesting to see how she finds more and more pieces of the puzzle she needs to solve. She is a fantastic heroine and I really enjoyed reading another part of her story. Advice If you love fantasy and like a good mystery the Night Angels Chronicles would be a great choice. I'd start with Key of Mystery and read the books in their correct order.

Great story

Sera's whole world is about to change. When her father dies under mysterious circumstances Sera wants to know what happened to him. He hasn't left his family anything but a black box. Inside is a key and Sera wears it around her neck. That's when she suddenly starts having horrible nightly encounters with awful creatures. Someone wants to harm her, but why? Does it have anything to do with her father's death? Sera thinks his disappearance might have something to do with a secret hidden beneath the city. Help comes from new people at Sera's school. They are there to protect her. That doesn't mean she can automatically trust them though. Do they act in her best interest? When almost all of her old friends suddenly dislike Sera because of what happened to her father she's in dire need of new friends. Fortunately she doesn't have to fight all of her battles on her own, but does that also mean that Sera will be all right eventually? Key of Mystery is an interesting story about a fascinating key. I love the idea of a mysterious key that makes its wearer powerful. Sera is a great main character. Before her father's death she was spoiled, but she sees the world through different eyes after everything that happened to her. I enjoyed witnessing that transformation. She's often strong, but isn't afraid to show weakness either. She's fiercely loyal and cares about people. That also means that she wants to protect them at all costs. The book ends with a big cliffhanger and I can't wait to find out what will happen to her next. K.H. Mezek is a good writer. I liked her choice of supernatural characters and the idea of a secret chamber that can be opened with the special key. There are vampires in this story and there are also creepy zombies. If you enjoy reading supernatural stories you should definitely get this book.

Loved it! Can't wait for the next book!
Written by KMontigny on 28th Feb 2016

I was gifted a copy for an honest review. This book was very intriguing, where do I even begin? It starts off with Sera at her fathers funeral, with her mom and brother and you learn a little about her lifestyle. She grew up pretty wealthy, and she's pretty shallow. Her mother is very shallow and I don't like her much, and her brother seems to be in a rebellious phase. They aren't exactly a tight knit family. I found Sera a bit annoying in the beginning because she seemed whiney, ungrateful and snobby. However, as the story progresses, things take a turn and flip her world upside down and she finds out who her friends truly are. We get to see her transformation, and it's a nice change from her former self. She learns of this whole other world that her father was engulfed in once she receives a mysterious key. She's determined to find out what really happened to her father as she believes things are not as they seem. Strange things start happening to her and she is unsure of who to confide in. Sera makes a couple new friends and tells them some of her theories, but not everything, as she's still a little weary on who to trust. She also gets confirmation about things that seem impossible from some out of towners, who she is not quite sure she can completely trust. This is the first book in this series, and I believe the authors debut novel. I have to say, she did an amazing job! It ends on a bit of a cliffhanger and I am dying to know what will happen in the next book. I'm hoping I don't have to wait too long for it!! Mezek does a great job at capturing and keeping your attention. The story line is great and not your typical paranormal story. That's what I like about it though. I think this is a great start to the series and she's definitely made a new fan. Can't wait to find out what happens in Sera's journey of uncovering the truth about this mysterious world that wants to stay hidden. B2B Kristina
