Blurb for My Unwritten Novel

Okay, mostly unwritten. I've finished the first chapter, almost 6,500 words in. Here's the blurb I'll be perfecting to market this bad boy.

Colleen is sixteen years old, has dropped out of school, and lives with her survivalist dad high in the North Carolina mountains. When FBI agents come looking for her missing brother to guide them into the wilderness to track down a bombing suspect, she’s the only one with the skills to find him. But when she finds that the agents actually suspect her brother is the bomber, she’s got to decide once and for all if she should trust her family or if this is her only chance for an escape to a normal life. That is, if she can make it down the mountain alive.
