About this book
In this high-adventure sequel to Downriver, Jessie returns to the Colorado River for a guided trip through the Grand Canyon—and the rapids are only part of the challenge. Tensions within the group, split-second decisions, and the raw power of the river test everyone’s courage and judgment. Fast-paced and full of whitewater action, it’s a great pick for middle-grade readers who love outdoor survival stories. Strong characters, vivid canyon scenes, and big stakes keep pages turning without giving away the ending.
Setting: Grand Canyon and Colorado River; contemporary whitewater rafting expedition
