Morgan D'Arcy is an English lord, a classical pianist, and a vampire. He has everything except what he desires most—Isabeau. As the Angel Gabriel he's steered her life and career choice, preparing her to become Lady D'Arcy. Many forces oppose Morgan's daring plan—not the least of which is Vampyre law.

Isabeau Gervase is a brilliant geneticist. Though she no longer believes in angels, she sees a ticket to a Nobel Prize in Gabriel's secrets—secrets that have led her to a startling conclusion. Gabriel isn't human, and she fully intends to identify the species she named the Angel Genome.

Morgan is ready to come back into Isabeau's life, but this time as a man not an angel. Will he outsmart his enemies, protect his beloved and escape death himself? For the first time in eternity, the clock is ticking.
