September Tide by Daphne du Maurier

Stella Martyn’s serene existence by the sea in Cornwall is thrown into turmoil by the arrival of Cherry, her young daughter, and Cherry’s attractive new husband, Evan. Repelled yet drawn by their Bohemian lifestyle, Stella finds herself swept along by a rising tide of emotion that threatens to engulf her. As her old friend Robert puts it: “You never know what will happen with a September Tide. More damage can be done at this time of year than in all the other months put together.”

Tempestuous drama from the author of Rebecca
