Five years ago, Evelyn and Philippa Hapwell cowered from air strikes in a London bomb shelter ... and were transported to another realm called the Woodlands. In a forest kingdom populated by creatures out of myth and legend, they found temporary refuge. When they finally returned to London, nothing had changed -- except themselves. Overcome with longing, Ev is desperate to return no matter what it takes. Philippa is determined to find a place in this world, and moves to America to escape the memory of what was. When Evelyn goes missing, Philippa wonders if Ev truly did find a way home, or if the weight of their worlds pulled her under.
