Jack Catcher's a kid during the Great Depression, and he lives in the Dust Bowl. His mother's died, and his father's committed suicide. You might think that Jack would be a little depressed, but he's a strong character, and when he gets a chance to strike out on an adventure with a couple of other kids -- Jane and her little brother, Tony -- he's all for it.
So this is a road novel, with the youthful trio encountering all manner of people and adventures, from the common folk to notorious gangsters to evil lawmen.
I particularly enjoyed the Burroughs references and the humor, but there's plenty more here to like. You can't go wrong with Lansdale. Check it out.
