Curses. When fairies stole her brother, Red vowed to get him back. Now trapped in the fairy realm, she begs to be seen before the fairy court where she strikes a bargain: Her brother in exchange for all thirteen charms from Tanya's bracelet.

Back at Elvesden Manor, Red, Tanya, and Fabian begin a desperate hunt, but as they soon find out, the fairies have done more than hide the charms; they've enchanted them with twisted qualities of the thirteen treasures they represent. And the longer the charms are missing, the more dangerous they become.

Can Red, Tanya, and Fabian find all thirteen charms? And if they do, will the fairies keep their promise?
