Imaginary Friends — Jan Ryan

Heather Greenwood is only five years old when her whole family is killed in a car accident. Sent to live with her Great Aunt Lily, she's fascinated by the old lady's faerie stories and builds herself a world full of Mother Nature's sons and daughters. They become her family, her imaginary friends. Thirty five years later, she returns to the cottage to care for her dying Aunt and to renew the friendships she lost so long ago.
