In the midst of maneuverings to create political alliances through marriage, sixteen-year-old Poppy, one of the infamous twelve dancing princesses, becomes the target of a vengeful witch while Prince Christian tries to save her.

Eleven-year-old Princess Celie lives with her parents, the king and queen, and her brothers and sister at Castle Glower, which adds rooms or stairways or secret passageways most every Tuesday, and when the king and queen are ambushed while travelling, it is up to Celie--the castle's favorite--with her secret knowledge of its never-ending twists and turns, to protect their home and save their kingdom.

"Castle Glower's towers have transported Princess Celie, her siblings, and her pet griffin, Rufus, to an unknown land. As they set out on a dangerous adventure to discover their whereabouts, they find an entire lost people, divided by the wishes of two wizards in a centuries-old quarrel over their beloved home--Castle Glower"--

When Petunia, youngest of the dancing princesses, is ambushed by bandits in wolf masks on her way to visit an elderly neighbor, the line between enemies and friends becomes blurred as she and her sisters get a chance to end their family's curse once and for all.
