My new book that I'm working on! This is Hura (the blonde) and Diablo (the boy with the paw print). Diablo is a demon who falls for the human boy. Hura make's a deal with Luc's (the devil, yes she's a women) son, Diablo, heir to the underworld. Diablo is to protect Hura until his death, then then though when he dies Diablo gets to feast on his soul.
