Graham Obermann is an established biographer of the Post-Impressionists. He is married to Celia Prosper, a modernist painter well-regarded by critics and collectors. As Obermann organizes a birthday party for Celia, looking after all the details, he describes in a single day the odd Prosper family and his attraction to his novelist brother-in-law Karl. Several significant events test all the characters in this family saga with subplots of many generations, and a new generation making its mark. * * * * Other books by Douglas Atwill, all from Sunstone Press, are "Why I Won't Be Going to Lunch Anymore," "The Galisteo Escarpment," "Imperial Yellow," "Creep Around the Corner," "The Oyster Shell Driveway," "Husband Memory Pickles," and "Douglas Atwill Paintings."
