Bitsy is no one’s ideal princess. She’s heard it all: that it’s a shame she’s so plain, so lacking in grace. That the best thing for her to do is simply wait (and wait some more) and hope some prince will grant her a happy ending. Then Bitsy pricks her finger on a spindle and falls down, down, down. Into a world where cutthroats and con artists are more common than curtsies. Where no one ages and everyone is beautiful. Where an inscrutable evil rests at its core.

Get ready to fly or die in the breathtaking follow-up to Fourth Wing and Iron Flame from #1 New York Times bestselling author Rebecca Yarros.

Annaleigh lives a sheltered life at Highmoor with her sisters and their father and stepmother. Once there were 12, but loneliness fills the grand halls now that four of the girls' lives have been cut short. Disturbed by a series of ghostly visions, Annaleigh becomes increasingly suspicious that her sister's deaths were no accidents. The girls have been sneaking out every night to attend glittering balls, dancing until dawn in silk gowns and shimmering slippers, and Annaleigh isn't sure whether to try to stop them or to join their forbidden trysts.

When a chance encounter sparks an unlikely bond between rival murderers Sloane and Rowan, the two find something elusive—the friendship of a like-minded, pitch-black soul.

A thorn witch with the power to walk between the realms of Life and Death finds herself at the center of a magical rebellion—and a dangerous romance—that could destroy her coven and her soul in this dark and decadent debut.
