Saved by the Trickster — Shona Husk

In a world of cold and Darkness, Lysanna is a Trickster, a demi-god charged with making people believe in Light and hope. She travels the world creating magic and wonder, taking human assistants to help on stage and warm her bed. Somehow they always betray her, and they always leave.

Zander is a fallen Celestial warrior. Cast out of heaven, he's been given one month to earn his way back. When he meets Lysanna, he knows what she is. What he doesn't expect to discover are the pleasures of being human, and the burning lust he finds in the Trickster's bed. Returning to heaven begins to lose its appeal, but he's sworn to fight the Darkness, to stop it from consuming the world -- which means possibly choosing between duty and Lysanna.
