Obsession: His Devotion is Lethal Obsession: His Devotion is Lethal is an addictive, fast paced romantic thriller that grabs hold from page one and refuses to let go. The story is packed with an intriguing plot that constantly shifts, keeping you on edge with unexpected twists that make it nearly impossible to put down. One of the standout elements is the witty banter between the main characters.

It’s gripping, heartfelt, and wonderfully entertaining.
I loved the feel of this book. It was a fast paced read and combined suspense and the character's individual responses to the events to make a highly entertaining and interesting read. I think she captured the symptoms and triggers of trauma and living with trauma really well, in a way that wasn't overdone, and I like that the FMC started out struggling with her issues and gradually as the story went on, found the strength to deal with them. Strong female characters are great but getting to read them build themselves back up is entirely different. I loved all the spice and that it wasn't central to the story, but part of it. The MMC was yummy. But I think I liked the secondary character better. For a psych thriller and suspense novel this book was funny. I was laughing at parts the whole way through. The FMC's thought process and sarcasm was so fun to read. I would definitely recommend this book. But I think more could have been done from the angle of the killer. it would have made it more interesting to read his POV with the rest of it.
Obsession: His Devotion is Lethal is a gripping psychological thriller that keeps you hooked from beginning to end. Erica Metcalf delivers a suspenseful story filled with tension, unexpected twists, and emotionally charged moments. The characters are compelling, and the atmosphere keeps you guessing as the mystery unfolds. The pacing is excellent, making it difficult to put the book down.

One of my favorite aspects was the dialogue. The witty banter between the characters adds humor and personality, creating the perfect balance against the darker, more suspenseful moments. Katie, Caleb, and Liam are all memorable in their own ways, and their interactions make the story feel engaging and authentic.
The romance and suspense are blended seamlessly, with emotional and intense moments that feel earned rather than forced. As the relationship develops and the danger escalates, the stakes become even higher, making it difficult to put the book down.
