Roundhill

She was an intruder to him at first. After all, the Roundhill is Evan's secret place - the spot he escapes to on school holidays. He doesn't want to share it with a strange girl in such old-fashioned clothes. But Alice has an intriguing way of knowing things - about him, about his house - that he has never told her. Odder still is that the more she talks about herself, the more mysterious she becomes. And how did she get through that locked door? At last Alice leads Evan to a special book and an incredible discovery - and the Roundhill was at the heart of the mystery all along.
