When environmentalism clashes with financial treachery, the results can be murder... A nature advocate, Erin Archer, is working to restore a now-flooded and dammed up Hetch Hetchy Valley in the Yosemite National Park to its original state. When her father, a private investigator and experienced mountaineer, dies in a rock-climbing fall, Erin doesn't believe it's an accident. Determined to find the truth, she uncovers a connection between her father's last case and Nick Oliver, a business intelligence analyst. Fired from his job in San Francisco, Nick is seeking refuge in the coastal redwoods when Erin brings his solace to a jolting end. Even though he doesn't think his work has any connection to her father's death, Nick can't resist her plea for help. However, Nick and Erin's sleuthing begins to make someone very nervous...and dangerous. Just how far is that someone willing to go to hide the truth?
