It’s been four years since Chris Arlin graduated with a degree that most people think she made up, and she’s still no closer to scraping up funding for her research into rare plants. Instead, she’s stacking shelves at the campus library, until a suspiciously well-dressed man offers her a lucrative position on a scientific expedition. For Chris, the problem isn’t the fact that they’re searching for the Biblical Tree of Life. Nor is it the fact that most of the individuals on the expedition seem to be fashionably lethal mercenaries. The problem is that the mission is being backed by SinaCorp, the corporation responsible for a similar, failed expedition on which her mother died eleven years ago. However, when Chris’s father is unexpectedly diagnosed with inoperable cancer, Chris sees only one solution. Vowing to find the Tree of Life before SinaCorp’s mercenaries, Chris recruits Luke, an antisocial campus priest undergoing a crisis of faith. Together, they embark on a desperate race to find Eden. However, as the hunt intensifies, Chris discovers growing evidence of her mother’s strange behaviour before her death, and she begins to realise that SinaCorp isn’t the only one with secrets they want to stay buried.
