for Bella at Midnight by Diane Stanley and Bagram Ibatoulline
Bella has grown up thinking that she was just a simple peasant girl. But suddenly, Bella's world collapses. First, her best friend, Julian, betrays her. Then she finds out that she is, in fact, Isabel, the daughter of a knight who abandoned her in infancy. And now he wants her back. Bella is torn from her beloved foster family and tries to accept her new life with her deranged father and his resentful wife. But when she finds out about a terrible plot that threatens the kingdom, she sets out on a journey that will lead her to a destiny far greater than she could have imagined.
