She’s not evil, but she has certain. . . urges.

Lane is a typical teenager. Loving family. Good grades. Afterschool job at the local animal hospital. Martial arts enthusiast. But her secret obsession is studying serial killers. She understands them, knows what makes them tick.


Because she might be one herself.

Lane channels her dark impulses by hunting criminals—delivering justice when the law fails. The vigilantism stops shy of murder. But with each visceral rush the line of self-control blurs.

And then a young preschool teacher goes missing. Only to return. . . in parts.

When Lane excitedly gets involved in the hunt for “the Decapitator,” the vicious serial murderer that has come to her hometown, she gets dangerously caught up in a web of lies about her birth dad and her own dark past. And once the Decapitator contacts Lane directly, Lane knows she is no longer invisible or safe. Now she needs to use her unique talents to find the true killer’s identity before she—or someone she loves—becomes the next victim.


Killer Instinct is a must-read book from start to finish. It’s thrilling, exciting, and entertaining, making Lane a character to keep your eye on, just like everyone around her under tight scrutiny. As the story starts, Lane shows interest for serial killers and does her best to understand how they think to the point of comparing herself to them. Having access to information about certain killers, do to her mother’s FBI job, Lane is well prepared when it come to profiling them, and as the book progresses, she uses this information to bring justice her own way and style.

I very much liked this book. Once I started reading it, I was excited to know how the story was going to develop. Lane was ready to deliver justice by her hands where it was being neglected with her own skills. She was a character knowing when to kill and when to let the villain live for the him or her to suffer the consequences of their acts. I liked her personality of not wanting to be involved with the typical drama of a teenager’s daily life. I felt she was mature enough to know how to handle her younger ‘perfect’ sister and someone’s crazy ex-girlfriend.

The interesting turning point begins when the Decapitator arrives in her life. A fascination for him strikes her and she will stop at nothing to find him when he approaches her with mysterious notes threatening her family. I liked how Lane thought that he was messing with the wrong girl. Once the Decapitator is introduced, the author throws every potential character to hide the real serial killer, which in my opinion just worked out well because at the end the Decapitator’s identity caught me by surprise.

The story does have its fun aspects, like how everyone keeps calling her vigilant persona Masked Savior and drawing her with a cape. It also has a touch of romance here and there, like her experiences of certain feelings for the first time. Another character that caught my attention was her hacker friend Reggie, though only appearing through phone calls, she’s clearly the friend you want to always keep around.

Towards the end of the story, as a reader, I just had my suspicions of everyone, which I like in a mystery book. You have to keep the killer or villain well hidden to surprise your reader at the right moment. Now that Killer Instinct caught my attention, I hope a next book comes out soon. There are still some questions unsolved and I’m interested to know how Lane’s life will keep changing after this book’s events. As I said, Lane is the girl you should keep your eye on, she still has a lot to show. I recommend you read Killer Instinct, give this thriller a try.
