Upon The Midnight Clear by Sherrilyn Kenyon
Ever think Scrooge had it right before the ghosts ruined his life? Meet Aidan O'Conner. At one time he was a world-renowned celebrity who gave freely of himself and his money without wanting anything in return... until those around him took without asking. Now Aidan wants nothing of the world - or anyone who's a part of it. When a stranger appears at his doorstep, Aidan knows he's seen her before... in his dreams. Born on Olympus as a goddess, Leta knows nothing of the human world. But a ruthless enemy has driven her from the world of dreams and into the home of the only man who can help her: Aidan. Her immortal powers are derived from human emotions - and his anger is just the fuel she needs to defend herself... One cold winter's night will change their lives forever... Trapped together in a brutal winter storm, Aidan and Leta must turn to the only power capable of saving them - or destroying them both: trust.
