War veteran Peter ash sought peace and quiet among the towering redwoods of northern California, but the trip isn't quite the balm he'd hoped for. When he retreats up a nearby sapling to escape a bear, he finds something strange: a climbing rope, affixed to a distant branch above. Up through the giant tree canopy, on a hanging platform, is a woman on the run. From below come the sounds of men and gunshots. Just days ago, investigative journalist June Cassidy escaped a kidnapping by the men who are still on her trail. She suspects they're after something belonging to her mother, a prominent software designer who recently died in an accident. Only one step ahead of their pursuers, Peter and June must race to unravel this peculiar mystery. What they find leads them to an eccentric recluse, a shadowy pseudo-military organization, and an extraordinary tool that may change the modern world forever.
