Estrella is a Marrano: During the time of the Spanish Inquisition, she is one of a community of Spanish Jews living double lives as Catholics. And she is living in a house of secrets, raised by a family who practices underground the ancient and mysterious way of wisdom known as kabbalah. When Estrella discovers her family's true identity - and her family's secrets are made public - she confronts a world she's never imagined, where new love burns and where friendship ends in flame and ash, where trust is all but vanquished and betrayal has tragic and bitter consequences.
