WHERE OR WHEN Leafing through his newspaper's literary supplement one day, Charles Callahan, a middle-aged insurance broker, spots a photograph of his first love, Siân Richards. Married, faithfully if not happily, with three daughters and a struggling business, Charles writes to Siân, a published poet, also married and mother of two children. Siân writes back, and as their correspondence develops into intimacy, three decades after their childhood affair, they agree to meet again. Swept up in the past and consumed by an obsessive love, Siân and Charles risk everything for each other, reaching across time to reclaim what they had in youth. "A thoughtful, beautifully written contemporary romance" (The Washington Post), Where or When is also a heart-wrenching, suspenseful story with a shocking conclusion.
