The Lost Island of Tamarind (The Book of Tamarind, Bk. 1)

It is not down on any map; true places never are.

Maya Nelson isn't your typical thirteen-year-old. She's spent her whole life living on the sea with her marine biologist parents, her younger brother, Simon, and baby sister, Penny. Maya used to love living on a sailboat, but lately, everything feels terribly claustrophobic. Maya longs to go to school on land. To make friends. To lead a normal life. But when a violent storm hits and Maya's parents are washed overboard, life becomes anything but normal. The children manage to steer the boat toward a mysterious island, to a place that doesn't exist on a map.

Welcome to Tamarind, where fish can fly, pirates patrol the waters, jaguars lurk, the islanders are at war, and an evil, child-stealing enchantress rules the jungle.

Maya never imagined she'd have to face so many dangers. But then, who could have imagined a place like Tamarind?
