Virgin Jackson is the senior ranger in Birrimun Park - the world's last natural landscape, overshadowed though it is by a sprawling coastal megacity. She maintains public safety and order in the park, but her bosses have brought out a hotshot cowboy to help her catch some drug runners who are affecting tourism. She senses the company is holding something back from her, and she's not keen on working with an outsider like Nate Sixkiller. When an imaginary animal from her troubled teenage years reappears, Virgin takes it to mean one of two things: a breakdown (hers!) or a warning. Dead bodies start piling up around her, so she decides on the latter. Something terrible is about to happen in the park and Virgin and her new partner, U.S. Marshall Nate Sixkiller, are standing in its path...

Virgin’s in a tight spot. A murder rap hangs over her head and isn’t likely to go away unless she agrees to work for an organisation called GJIC (the Global Joint Intelligence Commission). Being blackmailed is one thing, discovering that her mother is both alive and the President of GJIC is quite another. Then there’s the escalation of Mythos sightings and the bounty on her head. Oddly, Hamish is the only one she can rely on. Life is complicated.
