The Forgotten Garden (Kate Morton)

This story sprawls over more than 100 years to unravel the mystery of a 4-year-old girl found abandoned on the docks in Australia in 1913. She could tell no one her name or how she came to be there, and nobody ever came to claim her; all she had was a small suitcase with some clothes and a book of fairy tales. A local family took her in, but she spent most of her life trying to discover her past. The mystery was passed down to her granddaughter, who was finally able to uncover the whole story. It was engrossing, moving, horrifying and touching, all at once. I very much enjoyed it.
