For twelve year-old Samantha Torres, her Type 1 diabetes used to just be a frustrating nuisance - one more thing for her mother to tell her she wasn't being responsible about. But when her cruise ship crashes on a mysterious jungle island and separates her from her family, managing that chronic illness becomes a struggle for her life. Luckily, she receives some help from a 3,000 year-old woman named Belby, who claims that Samantha's powers indicate that she is supposed to protect the island from intruders. Specifically, she has to stop a bunch of creepy zombie-people - who most likely have kidnapped her mom - from reaching the magical tree at the center of the island. With just a single bottle of insulin, some awesome gravity-bending superpowers, and a quippy attitude, Samantha is guaranteed to succeed and prove to her mom once and for all that she can be responsible. After all, putting yourself in harm's way to fight a bunch of bad guys is super responsible…right?
