About This Book
The sharp snap of cracking branches fills the air, and the heavy, damp scent of jungle leaves wraps around you. Suddenly, you're not in the frozen Arctic anymore—you're surrounded by towering trees and mysterious creatures lurking just beyond sight. With food running low and strange dangers all around, how will eight kids survive when trust is as fragile as the jungle itself?
