It's been four years since Chris Arlin graduated with a degree in cryptobotany, 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 lethally fashionable 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 an incurable illness, Chris sees only one solution. Vowing to find the Tree of Life before SinaCorp's mercenaries, Chris recruits Luke, a sardonic campus priest undergoing a crisis of faith. Together, they embark on a desperate, wondrous race to find the lost garden of Eden.
