Born with powers similar to a vampire's, Lilith has spent her life hunting demons for Section Seven. On the same night as she watches a vampire kill her best friend, she is faced with her worst nightmare—a client who is not only attractive but a vampire.

Lincoln is a powerful pureblood with a problem. He's caught up in a prophecy and has little time left to unravel the mystery of the contract between his lord and the Devil before he dies. When witches foretell that a vampire hunter will save his life, he's prepared to work with his most hated enemy, but he isn't prepared for the forbidden desire he feels when he meets her.

Their mutual attraction becomes difficult to deny as they work together but when Lincoln reveals the truth about her powers, will Lilith find the strength to embrace a side of herself that she wished didn't exist? And when they discover Lilith's role in the prophecy, how far will Lincoln go to save her?

Dark, sensual and fast–paced, Seventh Circle is a story of forbidden love so strong that it will save the world.
