All Souls Lost by Dan Moren

Say hello to Mike Lucifer, Spiritual Consultant. He’s back in town to take care of business. Unfortunately, when business is good, things must be very, very bad.

After two years trying to run away from his past, Mike Lucifer’s back in his office less than ten minutes when a persistent young woman shows up asking for help: her boyfriend’s been possessed by a demon.

That’s exactly the kind of mess that drove him from his hometown of Boston to a sunny beach—and the bottom of a bottle—in the first place. But there are some problems that even booze can’t drown, and while Lucifer may be no hero, his dwindling bank account provides a thousand reasons to take the case.

No sooner is he back in the game then the complications and corpses start to add up. The boyfriend’s not possessed—he’s dead. The tech company where he worked is looking shadier by the second. And Lucifer’s client definitely knows more than she should…about everything. The deeper Lucifer digs, the more he wonders if whatever sinister entity lurks behind this case wants him to be the last to die…
