His Last Secret - Harriet Warren
From the moment Anna found that note hidden in Daniel’s pocket, I was completely hooked. Then came the knock at the door from the police and I knew there was no way I was putting this book down until I reached the very last page.
This book is packed with tension, secrets and twists that constantly had me second guessing everything I thought I knew. Every chapter seemed to unlock another secret, revealing more lies and hidden truths that pulled me even deeper into Anna and Daniel’s story.
Harriet Warren does an incredible job of building suspense throughout, keeping the reader on edge and desperate to uncover the truth. Just when I thought I had things figured out, another twist came along and completely changed everything. Wow… what a twist!! And oh, the heartbreak… some moments genuinely hit hard and left me completely emotional.
A gripping psychological thriller that will keep you turning the pages long into the night.

Thank you so much to Harriet for sending me an ARC copy of this book! I absolutely love a good thriller, and this one completely pulled me in. The suspense kept building with every chapter, and I found myself flying through the pages trying to figure out what was really going on. Every time I thought I had an answer, I was left with even more questions. The plot was so engaging, and that ending?! Talk about a cliffhanger! I was not ready for it and immediately needed more. If you love thrillers packed with suspense, mystery, and twists that keep you guessing, definitely add this one to your TBR. I can't wait to read more from Harriet!
