When she pricks her finger on a bone spindle, treasure hunter Fi is stuck with the spirit of Briar Rose, a prince under a sleeping curse, and must team up with a tough-as-dirt girl warrior to free the prince--and herself. Fi is a bookish treasure hunter with a knack for ruins and riddles, who definitely doesn't believe in true love. Shane is a tough-as-dirt girl warrior from the north who likes cracking skulls, pretty girls, and doing things her own way. Briar Rose is a prince under a sleeping curse, who's been waiting a hundred years for the kiss that will wake him. Cursed princes are nothing but ancient history to Fi--until she pricks her finger on a bone spindle while exploring a long-lost ruin. Now she's stuck with the spirit of Briar Rose until she and Shane can break the century-old curse on his kingdom. Dark magic, Witch Hunters, and bad exes all stand in her way--not to mention a mysterious witch who might wind up stealing Shane's heart, along with whatever else she's after. But nothing scares Fi more than the possibility of falling in love with Briar Rose.

Fi, her partner Shane, and Prince Briar Rose set out for the hidden city of Everlynd, hoping to break the curse, decipher the book code, and defeat the Spindle Witch.

Trapped in a tower with Briar Rose, Fi faces the Spindle Witch's threat and the imminent discovery of Siphoning Spells, while Shane seeks a weapon to save Andar and contends with the danger of Red's betrayal and the ruthless Spindle Witch's executioner, leading them to unravel the secrets of the Tomb of Queen Aurora.
