Divine's Emporium — Michelle L. Levigne

Maurice used his Fae magic to help the downtrodden and abused. But when he went too far, the Power-that-be decided he needed to learn humility, self-restraint, and mercy. They took away most of his magic, shrunk him down to 5 inches, and slapped wings on his back that no self-respecting Fae would be caught dead in. Then they exiled him to the Human realms, to work out his sentence helping Humans.
His destination: Divine's Emporium, a curiosity shop touched with magic, on the edge of the odd town of Neighborlee, Ohio.
His parole officer: Angela, the proprietress of Divine's Emporium, touched with magic and a shadowy past of her own.
His sentence: Help the Humans who come into Divine's to find answers, freedom, their own magic, and true love. Not necessarily in that order.
His problem: How does a five-inch-tall Fae, invisible to most Humans, win the heart of the ugly duckling who has caught his interest, his sympathy, and then his heart--when she can't see or hear him?
