"Can you ever run away from the circus?"--Cover.

Claudia doesn't know where she comes from. Sonia and Claude, her adoptive parents, don't want her knowing anything about her past - they won't even tell her how she got the burn that covers most of her face. But when she receives a mysterious message on her 11th birthday, everything starts to change... Soon Claudia is sent to The Cruet Establishment for Lost and Wayward Children, a boarding school for those who don't fit in. At first, she finds a world of intimidating teachers, unfair rules and truly disgusting soup, but before long Claudia begins to befriend her unusual peers, including a feral boy who was raised by a lion. All the while, she receives more cryptic messages that seem to bring her closer to discovering her true identity.
