The shut away sisters / Suzanne Goldring.

"Two ordinary sisters. A long and brutal war. A heroic sacrifice... London, 1915. As German bombs rain down on the East End of London and hungry children queue for rations in the blistering cold, fifteen-year-old Florrie is forced to grow up fast. With her father fighting in the muddy trenches, Florrie turns to her older sister Edith for comfort. But the war has changed Edith. She has grown quiet, with dark shadows under her eyes, and has started leaving the house at night in secret. When Florrie follows her sister through the dark and winding streets of London, she is shocked by what she discovers. But she knows she must keep her sister's secret for the sake of their family, even if she herself must pay the ultimate price... Years later Kate, running from her broken relationship, is sorting through her dead aunt Florrie's house, which she shared with her sister Edith. As she sits on the threadbare carpets, looking at photos of Florrie during the war, she notices the change in her aunt - from carefree young girl with a hopeful smile to a hollow-cheeked young woman, with dark sad eyes. Determined to put her family's ghosts to rest, Kate must unearth the secret past of her two aunts. Why is there a hidden locked room in the little house they shared? What is the story behind the abandoned wedding dress wrapped in tissue and tied up with a ribbon? And when Kate discovers the tragic secrets that have bound her family together, will she ever be able to move on?"--Provided by publisher.
