Flex Sefiroth is a fallen angel, and ancient by earthly standards, cast out of Heaven centuries ago for trying to protect one of their own. He had to find his own way in a world of men where fallen angels rarely survived their fall from God's good graces.
As the centuries pass he had learned to control every aspect of his life on Earth, but he suddenly finds himself in unfamiliar territory when he hears the most beautiful sound while visiting Paris, and soon becomes obsessed with finding its source. He searches desperately until at last he hears it once more. It leads him to a small bookshop where he finds the most exquisite thing he has ever seen in all his countless centuries of existence, Evette La Fontaine. But he soon discovers that over a century and a half of being shunned by every male she had ever encountered, both human and immortal alike, have taken a terrible toll on the lovely little bookworm.
Flex is determined to win her over and pulls out all stops to woo her. But will the timid little redhead succumb to his charms? Or will another's need for redemption ruin all his plans?
