The Deal (Devil's Brother #1)

Ever since Lucifer Morningstar got kicked out of Heaven, his brother Eae was appointed Demon Hunter. Living on Earth for thousands of years, Eae learned to love the incredibly naïve, amazing beings that are humans. Having spent the last century searching for a human strong enough to break out of a deal with his brother, Eae has grown weary and his time is running out. He doesn’t want to go back to Heaven, but he will have no other choice if he can’t do the one thing he’s on Earth for: release souls from the Devil’s possession.
