4⭐️ Romantic Suspense
Format: Kindle
⭐️⭐️⭐️⭐️ - I loved this book! Good plot, good story, & it kept my interest from beginning to end.
🌶️ - A little bit of spice sprinkled in.
Dark Romance is usually my genre of choice. However, Romantic Thrillers are quickly becoming one of my favorite genres that I wasn’t even quite sure existed. All of the Missing Pieces fits that genre perfectly. I really enjoyed Ridley’s character! For all the loss & trauma she has gone through, she is still so willing to help others. I loved her spitfire personality. This story had me feeling all kinds of emotions while making me giggle at times. I thought I had the unsub figured out about halfway through, but I was so very wrong! What a twist. Carter & Ridley’s relationship evolved perfectly. Ridley got the closure that she needed with her HEA. ‼️Possible spoiler ahead! ‼️I did find it hard to believe that Emerson was able to solve the case within a few minutes but wasn’t able to remember those same exact details over the course of 10 years? It felt a little too fast to me. Almost as if the author was trying to wrap up the story a little too quickly. On a side note, I wish there was a spin-off about Trey & Emerson!

The perfect romantic mystery
Format: Kindle
Honestly, this book’s hold over me was a little worrying.
The story opens with a tragic event, introducing Ridley Sawyer, who immediately captured my heart. She’s tenacious, motivated, witty, and complicated. I connected with her character so quickly that she felt like a friend by the second chapter—something that doesn’t happen often.
I also fell in love with her cat, Princess Tater, who had me giggling and kicking my feet. This little feline terror was so well-written that I was emotionally invested in her welfare. I would have rioted if anything happened to her or that adorable van she and Ridley lived in, which doubled as a mobile podcast station.
The story beautifully portrays the other fur babies as both sources of emotional comfort and brave protectors. I looked forward to each scene that included them.
Catherine painted a detailed picture of the small town and everyone living there. It perfectly sets the scene without upstaging the characters or the book’s mystery.
Colt was also a fantastic character. His grumpiness blended well with Ridley’s sunny personality, but they both had a darkness that few could see. Their tragic pasts brought them together and made them grow in ways I didn’t anticipate as the story unfolded.
I loved how the slow burn and spice were incredibly hot but subtle enough to enhance the story without overpowering it.
I couldn’t figure out who did it, so the reveal was a complete shock. I had doubts, but the author kept me guessing until the end. My hats off to her for sending me in every direction trying to solve this mystery without successfully figuring out who it was. I yelled, and my husband came running when it was revealed. 😂
I don’t give spoilers, but if you love small-town romances, captivating characters, and true crime mysteries, you’ll be hooked on this book. It had the perfect ending, resolving all my questions and giving me more than I expected.
This is my first Catherine Cowles book, but definitely not my last. Her writing style is engaging and punctuated with gorgeous sentences I eagerly highlighted on my Kindle to share with others.
I highly recommend curling up in your favorite chair, grabbing a snack, and getting lost in this incredible story. You won’t regret it.

Ridley & Colter 😍
Format: Kindle
Romance, Heartache, mystery & banter all wrapped up in one book.
I love me a Catherine Cowles book but having Ridley being a true crime podcaster was epic. I absolutely loved the mystery in the book and the heat between the two main characters. I also love a MMC alpha! You cannot go wrong with any of this authors book but this one was a great stand alone with connections to some of her other book characters.

Solidly Enjoyable Romantic Suspense
Format: Kindle
All the Missing Pieces by Catherine Cowles
Catherine Cowles delivers a compelling romantic suspense novel in All the Missing Pieces, the story of Colt and Ridley. Colt is the dedicated sheriff of Shady Cove, a quiet small town shaken by past tragedies, including the attempted kidnapping of his sister, Emerson. Ridley, a true crime podcaster, arrives in town searching for answers about her twin sister Avery’s disappearance on the night before their college graduation. What begins as an enemies-to-lovers dynamic between Colt and Ridley slowly transforms into a poignant story of healing, trust, and love.
This book is a perfect blend of heartfelt emotion and gripping suspense. Ridley’s grief and determination to uncover the truth about Avery are deeply tragic, adding layers to her character and her growing connection with Colt. The small-town setting and the suspenseful plot keep the pages turning, and the romance feels both organic and tender.
Cowles’ writing is on par with her other works—effortless and engaging. I found myself completely immersed, reading and listening to the book in a single evening. (Mild Spoiler!!!) My only critique is the identity of the killer, which felt too far outside the realm of possibility, slightly diminishing the story’s otherwise strong credibility.
Overall, All the Missing Pieces is a thoroughly enjoyable read, balancing emotional depth with suspense and romance. Fans of Catherine Cowles and the romantic suspense genre won’t be disappointed.

Great crime thriller! Fun,crazy, strong main character! Surprising & shocking twists! Perfection.
Format: Kindle
Wow what a great read this was !! I just finished it and truly enjoyed this. It had everything that I wanted in a book. I loved the mystery and the crime thriller in this mixed with some really fun found family, love, and crazy fun banter. My heart broke with the journey and the losses and the heartfelt struggles to move forward after loss. I loved how smart, strong and wonderfully crazy Ridley was. It made the story so fun even with the crime saga journey. Loved all the characters and how well they were described. You could honestly picture everything. This had a surprising twist at the end that made it all come together and really shock you. I actually yelled out "OH NO HELP HER! at one point of the book and walked away for a minute and then had to immediately jump back in. lol I really enjoyed this book! Really needs to become a series of this type of crime solving. Great writing. I have found a new great author to follow because I now have to have more of her writing.
