John Cleaver - Book #4
by Dan Wells
This is a quick novella by Dan Wells set in the John Cleaver universe. In the main series, John has discovered the existence of demons. In this story, we follow one such "demon", for lack of better term, named Elijah. This demon devours the memories of the recently deceased. All is well and good until in one such memory, he falls in love with Rosie, the wife of a victim, and then contrives to run into her again and again in the real world.
It's a quick, easy read, and if you enjoy the John Cleaver series so far, this is a nice bit of background into that universe. For 3 bucks, it's a good deal, too.
