In a time when Earth’s rising oceans contain enormous islands of refuse, the Amazon rainforest is all-but destroyed, and countless species edge towards extinction, the Virgin Zones were established in an attempt to combat the change. Off-limits to humanity and given back to nature, these thirteen vast areas of land were intended to become the lungs of the world. Dylan leads a clandestine team of adventurers into Eden, the oldest of the Zones. Attracted by the challenges and dangers posed by the primal lands, extreme competitors seek to cross them with a minimum of equipment, depending only on their raw skills and courage. Not all survive. Also in Dylan’s team is his daughter Jenn, and she carries a secret––Kat, his wife who abandoned them both years ago, has entered Eden ahead of them. Jenn is determined to find her mother, but neither she nor the rest of their tight-knit team are prepared for what confronts them. Nature has returned to Eden in an elemental, primeval way. And here, nature is no longer humanity's friend.
