Imp

Bound by an angel, Sam is the only demon allowed to walk among the humans and live—if she follows the rules. But when Sam’s brother, Dar, finds himself in hot water, following the rules becomes impossible. Retrieve an artifact from the vampires. Save Dar from centuries of enslavement and torture. All it takes is for her to perform a simple courier job, but with demons nothing is simple—especially when Sam must comply with the restrictions her angel has placed on her or face a punishment worse than death.
