In Good Harbor, Anita Diamant, author of phenomenal bestseller and book group favorite The Red Tent, explores the emotional lives of two mothers in present-day Cape Ann, Massachusetts. At the moment Kathleen, a graceful and maternal librarian, meets Joyce, a little younger, restless and funny, each woman has reached a turning point in her life. Kathleen, whose sister died of breast cancer fifteen years earlier, has just been diagnosed herself. Joyce, increasingly distant from her adolescent daughter, is taking stock of her marriage and struggling to write her second novel. When these two women meet for the first time, they recognize an immediate kinship. As they take long walks at Good Harbor beach, they begin to bare their intimate histories and help each other to heal old wounds. As a natural and resonant storyteller, Diamant brings to life the passions, traditions, and turmoil of these two women and their families, exploring the tragedy of loss, the destructive and restorative power of secrets and the tenderness of friendship and love.
