"Generations of the Roux family have learned this lesson the hard way. Foolish love appears to be the family birthright, in fact, which casts an ominous fate for its most recent progeny: twins Ava and Henry Lavender. Henry is mute for much of his young life, and Ava -- in all other ways a normal girl -- is born with the wings of a bird. In a quest to understand her peculiar disposition and a growing desire to fit in with her peers, sixteen-year-old Ava delves into her family's past and ventures into the wider world, ill prepared for what she might discover and naive to the twisted motives of others. Others like the pious Nathaniel Sorrows, who mistakes Ava for an angel and whose obsession with her grows until the night of the summer solstice celebration. That night, the skies open up, rain and feathers fill the air, and both Ava's quest and her family's saga build to a dark and heartbreaking crescendo."
