Marina's parents sent her to the Institute so the scientists there could find a cure for her shapeshifting powers. Marina was told there were no others like her. But when she accidentally gains access to the Internet and discovers there is a boy with the same powers living near an island to the south, she also uncovers a bigger mystery. Why has Dr Shaw lied to her about Fynn? What was in the canister she brought to shore as part of her 'testing'? Is Dr Shaw really searching for a cure for her? Or is he working on something much more sinister...?
