What an excellent read! I loved Anonymous Killer by KC Wilde. This paranormal, female lead detective (Tracy) suspense was engaging from the start. I loved everything about this romantic suspense. The detailed world building really places the reader into the story. The characters are well-written with depth, making them relatable. Tracy’s family, sister, colleagues, and mate/love interest (Luke) are all woven really well into Tracy’s story, life, and work. (I also loved the interactions of Tracy & her sister – funny and such a nice addition to the story. The elements of the suspense with several twists, turns, and unexpected surprises make this a uniquely worthy read! The suspenseful plot drew this reader into the story, kept me entertained, wondering what would happen next. Anonymous Killer is Book 2 of the Shadowbound Mysteries. It is a compelling and rewarding read and highly recommended.

So Anonymous Killer is the second book in the Shadowbound Mysteries series.

Our FMC Detective Tracy Lane is trying to track down a villain who appears to be one step ahead of the game. Unknown to Tracy though she is now in the crosshairs as it appears she is the target in this cat and mouse game.

The plotline has twists and turns which kept me on the edge of my seat, and it also has you guessing if the killer is someone closer to home.

I thoroughly enjoyed the storyline which was really well written; it is actions packed with some romance and suspense thrown into the mix. To top it off it leaves you wanting more as it’s left on a cliff-hanger so can’t wait for the next instalment.

Thank you for letting me be apart of the ARC reader team.

This second book of The Shadowbound Mysteries is a wonderful addition to the series. Tracy and Luke face a truly evil criminal who seems to know Tracy intimately and is always at least two steps ahead of the detective in her criminal investigation. Throughout the entire book I kept looking for clues as to who the villain might be and couldn't find any, so when the reveal was given at the end, I was definitely surprised. The story was action packed, cleverly written, and Luke and Tracy's continued romantic relationship heartwarming. It was so easy to get drawn into this story which made this a real page turner for me. I will be anxiously waiting for Book 3.

I have been eagerly waiting to read this second book in The Shadowbound Mysteries series. It didn't disappoint; it's an excellent addition to the series.

Tracy and Luke are facing an evil criminal who somehow seems to know Tracy very well and seems to be able to anticipate every move she makes in her criminal investigation.

Although I kept trying to guess who the villain might be without success, and when they were finally revealed at the end, it was a surprise.

The book is well and cleverly written, not only action-packed, but also heartwarming. I am now eagerly waiting for the next book.

Anonymous Killer is the second title in the Shadowbound Mysteries series. I would strongly suggest reading this series in order, if at all possible.

Tracy is hunting down a villain who seems to constantly be one step ahead of her, and closing fast on their target…her. Her unique talents, and help from the man no one else can see will fuel this race to find a killer in time.

I enjoyed Anonymous Killer by KC Wilde; it’s well-written, engaging, and emotional, with lots of twists and turns along the way to discovering the true identity of one nasty piece of work.

Ahhh, come on!! Another cliff hanger! Ok. Seriously, this book is so good, especially if you read the first one. But dang it now I need the next one because there is just too much unknown. I was on the edge of my seat reading this! I was super surprised at who the murderer was. That is not someone I had pegged. But it makes so much sense. Definitely read this book! But read the first one first. It'll help make things make me sense, especially everything with Luke.

Tracy is a superstar with her ability to solve cases as a police detective. She has a great partner and she really thinks outside of the box. That is until it becomes personal. She is hunting down a killer and then she realizes she is the target. So much drama!!!!!!!! And spice. I love this author, she makes me laugh so hard. Tracy is so mouthy and it is so funny.

This is book 2 of The Shadowbound Mysteries. It is a chilling, thrill of a ride story that had held my attention throughout the story. It is a murder mystery that has detective Tracy Lane hunting a killer that is closer than she knows. I liked the twists and turns in the story. It does end in a cliffhanger.

This is book 2 in the series. I did not read book 1 in the series so I was confused in the beginning. Book 2 does end on a cliffhanger. The characters Tracy and Luke were well-written. The details were great and I didn't see some of the twists. If you like paranormal shifter mystery books then you will like this one. I thought this book was amazing.

[Diane · Rating 5 out of 5]

This is the biggest betrayal ever! This book had me turning the pages to see who the serial killer was and why they were targeting Tracy. The author also gives us a bit more about Luke and what happened to him. I would recommend reading this book.
