'The South American Boreal: one of the last truly unexplored jungles on our planet. In its dark heart is an ancient crater basin, sealed in by a living cage, making it a time capsule for an ancient, deadly ecosystem.

'Matt Kearns, Carla Nero and a team of scientist explorers have found their way in. In the crater's sunken interior are creatures from a primordial nightmare. Dangers lurk in every treetop, under every rock or loom monstrously over them. It is a place where mankind is out of time.

'Matt and Carla must find out how the terrifying parasite wreaking havoc in the United States can be controlled while staying ahead of things that defy belief and shake their understanding of evolution on our planet.

'Trapped, with time running out, the team of explorers will find themselves a part of a food chain ... and nowhere near the top.' (Publisher's blurb)
