Vanishing edge : a novel
(Book)

Sequoia National Park. A park ranger discovers an abandoned campsite with an empty tent and high-end technical gear scattered on the shores of an alpine lake. Former FBI agent Felicity Harland is now a federal agent with the Investigative Services Bureau, tackling crimes that occur on National Parks lands. Brought in as chief investigator, she finds the company that set up the camp won't reveal their client list, leaving her with zero clues. When she meets Ferdinand Huxley, a Navy SEAL turned park ranger, she begins to see the value in not just working with a partner, but trusting one, in order to learn the truth behind the campers' disappearance. -- adapted from jacket
