Identical twins, Georgia and Bessi, live in the loft of 26 Waifer Avenue. It is a place of beanbags, nectarines and secrets, and visitors must always knock before entering. Forced to create their own identities, the Hunter children build a separate universe. It is when the reality comes knocking that the fantasies of childhood start to give way.
As a child Lucas assumed that all children who'd lost their parents lived on water. Now a restless young man, and still sharing the West London narrowboat with his down-to-earth sister Denise, he secretly investigates the contents of an old wardrobe, in which he finds relics from the Midnight Ballet.
