Hidden in the heart of the rainforest lies a secret... can three friends can survive long enough to find it? An action-packed jungle adventure, perfect for fans of Katherine Rundell's The Explorer and M.G. Leonard's Twitch.

Billionaire beauty mogul Anura Hegarty has pledged to acquire as much of the rainforest as possible to preserve it. But when armed guards appear and bring in portable terrariums to capture wildlife, Jessica and her friend Renata realise something much more sinister is going on. The rainforest holds a frog with a secret to staying young forever, and Jessica and Renata know they must find and save it first! Together with Briony-Rose, the girls journey deeper into the rainforest.

Danger and betrayal lurk in every corner, and soon they're running for their lives, dodging blow darts and falling into traps. Will the children make it out of the forest alive?
