Part ghost story, part novel of suspense The Marsh House is the haunting second novel from the author of The Night of the Flood where two women, separated by decades, are drawn together by one mysterious house on the North Norfolk coast.

December, 1962. Desperate to create a happy Christmas for her young daughter, Franny, after a disastrous year, Malorie rents a remote house on the Norfolk coast. But once there, the strained silence between them feels louder than ever. As Malorie digs for decorations in the attic, she comes across the notebooks of the teenaged Rosemary, who lived in the house 30 years before. Trapped inside by a blizzard, and with long days and nights ahead of her, Malorie begins to read. Though she knows she needs to focus on the present, she finds herself inexorably drawn into the past....

July, 1931. Rosemary lives in the Marsh House with her austere father, surrounded by unspoken truths and rumours. So when the glamorous Lafferty family move to the village, she succumbs easily to their charm. Dazzled by the beautiful Hilda and her dashing brother, Franklin, Rosemary fails to see the danger that lurks beneath their bright façades....

As Malorie reads Rosemary's diary, past and present begin to merge in this moving story of mothers and daughters, family obligation and deeply buried secrets.
