The magic half

Eleven-year-old Miri Gill feels left out in her family, which has two sets of twins and her, until she travels back in time to 1935 and discovers Moly, her own lost twin, and brings her to the present day.

On the afternoon that eleven-year-old Miri spots a piece of glass taped to the wall of her room, her world changes. Undaunted by the barest of clues, her mean cousin, and the mystery of time, Miri finds magic is really just a way of setting things right.
