Seven-X by Mike Wech

 I quite enjoyed this book about a reporter who goes undercover in an asylum to find out the truth about disappearing death row inmates.
The story was fast paced and quite tense and atmospheric,  well written with easy to understand language and a solid plot, the only reason I gave four stars instead of five is that I found the ending unsatisfactory and wanted to know more about what happened.
All in all, definitely worth a read if you like horror, demons and possession.
