With older twin brothers on one side and younger twin sisters on the other, Miri feels left out in her own family. But one afternoon, in her tiny attic bedroom, Miri finds a mysterious piece of glass. And when she peeks through it, something strange happens. Miri is suddenly face-to-face with Molly, a girl just her age but from the past, a girl that insists this is her room and that Miri has come to save her. This is the something special both Miri and Molly always wished for. But when their wish comes true, they discover their adventure together is just beginning.

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 Molly, her own lost twin, and brings her back to the present day.
