Not all is well at Tamarack Reserve in Bank's absorbing tale of class, politics, family and lunacy -- set in the Adirondacks in the 1930s. Loosely based on the life of noted illustrator, womanizer and independent-thinker Rockwell Kent, the Spanish Civil War and Hindenberg also intrude on the cozy familiarity of the startlingly beautiful summer retreat.  (NYS69, $24.95)
