Damnation is John Severne's inheritance, and stalking the accursed his legacy. Kat D'Arcy has her own ill–starred birthright. The strange gift that runs along her maternal line dooms her to a life trapped between daemons and those who pursue them. But Severne is unlike any daemon hunter she's ever known. The Brimstone in his blood arouses every fiber of her being.

For Severne, Kat is the key to his salvation...until she becomes much more than that. As the ultimate danger closes in on them both, Severne must decide if he can abuse Kat's trust–and betray his own heart.
