Rosa Martinez is seriously ill. She has the loving support of her mother and grandfather and a doctor who takes good care of her. But she also has a secret weapon. Rosa can summon five tigers to come to her aid when she's sailing or in big trouble. Her disease may think it has the upper hand for now, but wait until it encounters Gautama, Airk Vashti, Selena and Quan--the five fierce tiers of Rosa Martinez. Young readers will delight in their daring adventures and who knows: they may even be able to call forth guarding animals of their own when they need them.
