Some old flames are too hot to handle.

Something demonic is starting fires all over town, and it's up to hunky detective Lars Thornsson and his partner, Chelle Rochelle, to solve the case. The attacks have neither rhyme nor reason—and when Lars identifies the arsonist, he realizes his troubles are just beginning. Not only is he injured as the firestarter gets clean away, but Lars manages to mortally offend his succubus lover, Rael, in the process.

Rael has problems of his own: his cheating ex, Levi, wants him back. And Levi's a powerful demon who won't take no for an answer. With Levi ready to attack Lars to get what he wants, Rael has to work out what he's willing to do to save his lover. Up to and including sacrificing himself.
