Satan's Sword by Debra Dunbar — book slip

Samantha Martin is an imp, bound by an angel who allows her to live among humans as long as she follows his rules.

When her brother, Dar, finds himself in trouble, he needs her help to retrieve an artifact from the vampires, or a powerful demon he owes a favor to will enslave and torture him for centuries.

It should be a simple courier job, but with demons, nothing is simple.

Sam reluctantly attempts to help her brother, trying not to antagonize the vampires or the demon pursuing him, all while chafing under the restrictions her angel has placed on her as a bound demon.
