In this third installment of “The Adventures of Wilder Good,” Wilder and his “secret” girlfriend, Sunny Parker, set out with Wilder’s mentor, Gale Loving, for a day of fly fishing on the Rio Grande. But in the Colorado wilderness an afternoon of fishing and fun can shift suddenly to a life-and-death challenge. When Gale is injured, Wilder and Sunny must take charge. Together, the two learn what it is to aid and protect a friend. With no one to turn to, they have to make their own decisions and rely on their own skills as darkness falls and they prepare to spend the night in the canyon tending to Gale.
