r After series of fairy tale retellings from the point of view of the siblings in the background, this is the thrilling and mysterious story of Cinna and her older sister, Rapunzel, who was stolen from their castle as a baby. Now she's back, leaving Cinna with more questions than answers.

Princess Cinna has grown up longing for her older sister, Rapunzel, who was kidnapped before Cinna was born. Now that Rapunzel has returned home, Cinna couldn't be happier. She can't wait to help Rapunzel take her rightful place as heir to the throne.

But Rapunzel is not what anyone--including Cinna--expected. And whoever took her might still be lurking in the castle. When magical creatures begin attacking both princesses, Cinna finds herself with no one to trust...except, maybe, Rapunzel herself.

Will she risk everything for a sister with whom she may have nothing in common except their long, magical hair?
