Unbound by shadows
(Book)

"Selene has never been one to make a fuss. She doesn't mind it when the barista gets her order wrong, someone cuts her off in traffic, or she has to drop everything to mediated her family's latest crisis. But when she goes through a portal to the matriarchal dimension of Aurelia, she discovers that being nice doesn't always pay. Especially when she meets a demon whose smoldering gaze makers her wonder why she ever craved a life so ordinary. Samael is a vengeance demon with a drive to punish wrongs. Kidnapped from the Underworld, and brought to Aurelia as a boy, his demonic tendencies make him an outcast in a realm he can't escape. When he becomes Selene's guardian on a quest for a stone that could send her home, he plots to sacrifice her and steal it for himself. But as they travel together, their attraction grows. Until one day, they each must choose between finding escape and surrendering to temptation." --page [4] of cover
