The time-travelling classic about boarding school life, the First World War and the fear of forgetting who you really are.'Suppose you got stuck in here, and Clare there in your time. Just suppose you did?'Charlotte Makepeace's first day at boarding school is a bewildering blur of unfamiliar faces, timetables, rules and lists. All the other girls know the routine, and each other -- no one invites her into their exclusive circles of whispers and giggles. But on Charlotte's very first night something mysterious starts to happen. She wakes up in the same bed, in the same dormitory, in the same school. But something has changed. Charlotte has slipped forty years back in time.
