Hey, Trackers. I'm River--"part hound dog and a whole lot Cherokee," as my frenemy Kat says. I've been showing Kat how to track animals all summer long even though we argue about everything under the sun. When we find a buried map in a cave while waiting for a storm to pass, it thrusts us into the adventure of our lives. But hunting for possible treasure puts our already fragile friendship to the test. Can you imagine if we did find loot, like a chest of gold or something way cool like that? Kat could take in rescue horses at her parents' farm, and I could buy this awesome colt Flash I love so much! While searching for untold riches, we also have to deal with bullies, competing clubs, farm duties, frisky horses, and ferocious beasts that can claw your heart out. Will this treacherous journey turn us into good friends or make us mortal enemies forever? Join us in our heart-pounding quest while we try to not break our bones ... or our spirits.
