Left in a remote mountain pasture to care for 6000 sheep, a Wyoming rancher's 14-year-old son has a typical Paulsen series of adventures. Tink, loyal hand who usually watches the herd, is dying of cancer, and John's widowed dad is with him; the ranch's taciturn other hand helps get the sheep to the haymeadow and leaves John with little instruction. But the boy is capable and courageous; in just two days, he has to deal with a skunk, a rattlesnake, a wounded dog, a stampede, a flash flood, a pack of voracious coyotes, and an injury that nearly kills him; remarkably, he recovers with the loss of a few sheep and the labels off his canned goods—only to confront a vicious bear. After 47 days, his dad comes to report that Tink, miraculously, is recovering; he plans to leave next morning but—after the first real talk father and son have ever had—decides to stay on for the summer's last weeks. Good enough as an adventure; Paulsen's trademark run-on sentences keep it moving, and he certainly understands coping with the wild, though the perils here are so unbelievably many that they become laughable. Meanwhile, John's fixation on the self-reliant great-grandfather who founded the ranch is not well enough integrated with either the action or the present-day relationships to serve its ostensible purpose of motivating John's character and behavior. An entertaining yarn, but a minor literary effort. (Fiction. 10-14)
