Only Walter Platt's father was willing to forfeit tribute to the patroon system which prevailed in the Hudson River Valley of the 1840's. But fifteen year old Walter, and his older brother Gerritt, ranged themselves on the side of the anti-rent movement. After the death of beneficient and bountiful Patroon Van Rensaleer, his descendants pressed the farmers for payment and services on land they could not own. Harriett Carr's other historical books have included Against the Wind and Wheels for Conquest. Now she portrays divided family loyalties and defiance in the Hudson River Valley with commendable skill. But, for juvenile readers, interest will probably be limited to New York State and environs.
