Thirteen-year-old Tyson loves hanging out with his roughneck Grandpa Gene, who's a lot more fun than Tyson's ex-best friend, Brighton. These days, Bright just wants to be seen with the cool jocks who make fun of Tyson's Taylor Swift obsession and dorky ways. So when Grandpa Gene has to move to a nursing home that can manage his kidney disease, Tyson feels like he's losing his only friend. Not only that, but Tyson was counting on Grandpa Gene to take him on his first big hunt. So in defiance of Mom and Dad's strict orders, and despite reports of a scary, stalking, man-eating grizzly named Sandy, the two sneak off to the Grand Tetons. Yes, there will be action, like shooting and dressing a six-hundred-pound elk. Is Tyson tough enough? There will be heart-pounding suspense: is Grandpa Gene too sick to handle the hunt, miles away from help? And, oh yes, there will be bears.
