An old camper van was all Ryan Browning's mother left him when she died last year. Ryan, a thirty-something physicist, has just been fired and could be facing prosecution. It might be a good time to hop in that old van and head out on a long road trip, perhaps to never return. When he goes to the bank to close out his account, Ryan meets the lovely customer service rep, Amanda Seward, who has a few issues of her own. And that's just the first unexpected encounter on a two-thousand-mile trek through the scenic American West. But the Mountain Goat takes Ryan and Amanda on a deeper road trip through the intersections of art and science, grief and faith, and love. And leads them face-to-face with a deadly threat far greater than they can imagine.
