A girl. An iguana. An island. And e-mail. Meet Nim–a modern-day Robinson Crusoe! She can chop down bananas with a machete, climb tall palm trees, and start a fire with a piece of glass. So she’s not afraid when her scientist dad sails off to study plankton for three days, leaving her alone on their island. Besides, it’s not as if no one’s looking after her–she’s got a sea lion to mother her and an iguana for comic relief. She also has an interesting new e-mail pal. But when her father’s cell-phone calls stop coming and disaster seems near, Nim has to be stronger and braver than she’s ever been before. And she’ll need all her friends to help her.

This time Nim’s the fish-out-of-water as she stows away on a cruise ship to save her kidnapped sea lion friend. Accompanied by her likeable iguana, Fred, the island girl lands with a splash in Manhattan, on the run from of a very Bad Guy, and on her way to reunite with her friend, cowardly adventure novelist Alex Rover. Kids who are interested in animals and animal welfare will enjoy this warmhearted story’s combo of suspenseful high-seas happenings, New York City excitement, and family drama.

In her third gripping adventure, Nim unearths an amazing opalized fossil, but this discovery puts her island in terrible danger Nim lives on an island with her father, Jack, a marine iguana called Fred, a sea lion called Selkie, and their friend Alex Rover, the adventure writer.

But two of the scientists have plans other than studying algae. By the time Nim discovers what they really want, and what they will do to get it, the children are in grave danger. And so is the island! Nim must choose between saving a natural treasure and saving someone's life.
