Take Me to the River by Will Hobbs is on the 2012 Texas Lone Star reading list. It is definitely a book of survival. Not only do two 14 year boys raft the Rio Grande by themselves, they accidentally do it in a hurricane. They also run into a very dangerous kidnapper.
While reading this book, I learned a lot about the canyons of the Rio Grande. Here is some more information for you to explore from the National Parks Service! They show nice pictures of the canyons and even tell you how to plan for a boat trip.
