Unbound by Shadows by Avalon Griffen

Transported to another world, tempted by a dangerous passion.
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 mediate 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 makes 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.

Unbound by Shadows is a standalone novel, the first in an interconnected fated-mates series that blends paranormal romance and fantasy in a setting rooted in urban mythology. Perfect for fans of Sarah J. Maas, Ruby Dixon, and Kresley Cole.
