Dante is a witch (warlock, actually) living in an apartment in the city with his best friend (maybe more than best friends?), the vampire Phineas. By day, Dante does magic for paying customers. By night, he’s running errands with his drug dealing roommate. Widely considered one of the most powerful witches in New Toulouse, Dante’s one weakness is the illness that killed his mother, his father, and is slowly eating away at himself. Affectionately called the Demon Curse, it is, of course, the only illness which he has not been able to cure with magic. The only thing keeping him alive? The drug Phineas deals, Demon Drug.

When a shapeshifter named Gwen comes to Dante for help without a penny to her name, Dante’s ready to throw her out the door. But Gwen’s too stubborn and has her own problems to deal with; a vampire who won’t leave her the hell alone and a drug addiction she can’t feed. When she digs up an old picture of Dante’s family to use as blackmail, Dante’s whole world turns upside-down. A dark family secret has him rushing to find a cure for the Demon Curse while unknown supernaturals are trying to kill his roommate and the drugs aren’t working as well as they used to.

Of course, Phineas knows a cure for the Demon Curse. A bite to the neck and a little exchange of blood. But Dante would rather die than become a vampire, and he’s made this clear time after time. But if there’s one thing on this goddamn planet Phineas cares about, its Dante, and with Dante’s clock running down, he’s willing to not so selflessly sacrifice Dante’s soul to keep him alive.

Especially since he knows who’s waiting for Dante on the other side.
