Sabrina Castro, an attractive woman with a strong New England heritage, is married to a wealthy, older California physician who no longer fulfills her dreams. An almost accidental misstep leads her down the slow descent of moral disintegration, until there is no place for her to go but up and out. How Sabrina comes to terms with her life is the theme of this absorbing personal drama, played out against the background of an old Peninsula estate where her mother lives among her servants, her memories of Boston, and her treasured family archives. "A Shooting Star" displays the storytelling powers that Wallace Stegner's fans have enjoyed for more than half a century.
