From the description:
"Maud Flynn is known at the orphanage for her impertinence. So when the charming Miss Hyacinth chooses her to take home, the girl is pleased but baffled, until she learns of her new role: helping to stage elaborate séances for bereaved patrons. As Maud is drawn deeper into the deception, playing the "secret child," she is torn between her need to please and her growing conscience. It takes a shocking betrayal to make clear just how heartless her so-called guardians are. Filled with fascinating details of turn-of-the-century spiritualism and page-turning suspense, this novel from Newbery Medalist Laura Amy Schlitz features a feisty heroine whom readers will not soon forget."
