Showing A Small Sacrifice by Ellen Hart

When Cordelia Thorn ventures to Summer Green, Wisconsin, for a reunion with some old college friends, she finds trouble in paradise. Twenty-plus years have definitely changed things. Soap opera star Diana has become an alcoholic. Curt and Annie's marriage is falling apart. Orson is hostile and surly. Theo is secretive. Alarmed when one of her friends unexpectedly dies, Cordelia sends for her old friend Jane Lawless to do some quiet snooping. Together they follow their hunches--into the not-so-carefree past and back to the troubled present, where they find a single match could blow up all their lives.
