New York Times bestselling author Tamsyn Muir returns to blend a subversive fairy tale adventure with a desperate dungeon crawl.

THE TOWER BROUGHT THEM TOGETHER. TRUE LOVE MADE THEM WORSE.

The princess in the tower is a classic for a reason. Witch kidnaps princess. Witch puts princess in tower guarded by monsters. Prince kills monsters, rescues princess: happily ever after, roll credits. Princess Floralinda's story goes a little differently.

Her witch was an artiste, and she got carried away. After a dozen or so princes died on the very first floor, the rest decided there were easier paths to wedded bliss. So Floralinda sets out to rescue herself, armed only with a breadknife, a good upbringing, and a captive fairy named Cobweb.

THE ONLY WAY OUT IS DOWN

Unfortunately for Floralinda, the trouble with the tower is only beginning. On the outside, succession looms. The Fairy Courts call. A princess would have no hope of surviving all that is to come... but maybe a monster could.
