The Life and Undeath of Jack Faust

Jack Faust is just like everybody else--if everyone else was an undead, mostly-frozen winter hellion caught between this world, the next, and all the options that entails.
Long story short, he'd really like to get back into Hell. He's been alive too long, and well... after what he's done, Heaven isn't quite on the table.
Admittance back into Hell after getting kicked out will take something bigger than he's ever done before: human sacrifice.
Jack's not picky; virtually anyone will do. So when he encounters a difficult security guard standing between him and the book he needs, he thinks, why not?
Unfortunately for Jack, Finnegan is much more than he bargained for.
