I really enjoyed this book which is not always the case with short stories! The author did a great job keeping me engaged from start to finish — every chapter made me want to read “just one more.” The suspense, twists, and character development were well done. Mariah Stewart has a way of building tension while still giving you characters you actually care about. Definitely one of those reads that keeps you turning the pages late into the night. If you like mystery and suspense with a little emotional depth, this one’s worth picking up!

In my former life, I read a ton of 'romantic suspense'. So, it has been a hot minute since I have read Mariah Stewart. It was ok. A former detective, who now works for a nonprofit, takes on a case of her former chief.

Very short story

It was good but I was shocked that it was so short. I would have liked a longer read for .99cents
