Grayfox (The Journals of Corrie and Christopher)

When the stories of the first Pony Express riders hit California's newspapers, Corrie Belle Hollister's brother, Zack, jumped at the chance to finally get away from his home in Miracle Springs. He reckoned that everything would be different and he'd be happy if he was free and taking care of no one but himself. And the further from his pa, the better.

But Zack Hollister finds that the Pony Express Trail holds much more for him than the promise of adventure, independence, and great pay. It's a challenging and dangerous road that leads the boy to cross over into manhood and the solitary confrontation with who he really is.
