Mercy: the deadliest Sin is the second book in the Why we don’t Die in Dreams series by Debbie Zello and is a continuation from the first book and not a standalone. Debbie is a very clever writer in the way she has written this dark and twisted tale of a being who has no conscious. A creature you can only hear about in nightmares. Something you wouldn’t wish on your worst enemy. Something so heinous that you just can’t stop reading about. There are a lot of twists and turns that but boy did Debbie twist it all up and deliver and ending I. Did. Not. See. Coming!
I recommend reading this story but beware you will be on the edge of your seat and hiding behind your hands.
