"Camping doesn't lead to kidnapping... usually.
When Emily goes on a group camping trip in Northern Arizona, she suspects her biggest danger will be mosquito bites and bear-sightings. The trip becomes far from relaxing, however, when she hears from a family friend that they can't get in touch with her dad. Unable to call, due to spotty cell phone reception, she manages to send a text asking for Brent's help in checking on her dad.
But the spy has been incommunicado for several days, and it turns out he's up North too--trying to locate a missing ICS agent with information about the Ten Thousand."
