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...

Praise for ALL SOULS LOST

"Mike Lucifer is one hell of a private eye, and his story makes for a fun bump in the night ride that zigs and zags in delightfully unexpected ways." -Simon R. Green, New York Times bestselling author

"ALL SOULS LOST is a delicious mashup of old-fashioned noir, skin-crawling necromancy, and modern espionage, with a fistful of Boston attitude for good measure. The result is a deeply entertaining mystery, and my favorite Moren novel to date. More Mike Lucifer, please!" -Helene Wecker, New York Times bestselling author of The Golem and the Jinni

"ALL SOULS LOST is a crackling modern mystery infused with vintage noir vibes. It's the very best and coolest of old and new, but don't loan it out. You'll never get it back." -Cherie Priest, author of Grave Reservations and Flight Risk

"In ALL SOULS LOST, Moren summons up a potent blend of wit, noir, and the supernatural for a devilish hardboiled read." -Eric Scott Fischl, author of Dr. Potter's Medicine Show
