Winterborne Home for Vengeance and Valor
When 11-year-old April joins a group of kids living at Winterborne Home she doesn't expect to be there for very long. But she soon learns that this home isn't like any of the others - especially when she unearths the secret of the missing-and-presumed-dead billionaire, Gabriel Winterborne, who is neither missing nor dead but is actually living in a basement lair, sharpening his swords and looking for vengeance.
