Mike Fowler thinks the small desert town of Ambrosia is a dry, forsaken blip on the edge of civilization. He has no friends, no fun, and no answers to the agonizing disappearance of his dad in a top-secret military mission. But that could all change after Mike stumbles onto his dad's puzzling journal in the old B-17 out back. The mysterious entries in the journal lead him to a hidden canyon! Something big - maybe a covert military operation - is going on in that secluded canyon.
