The narrator Aliya reminds one of Scherezade as she spins out one story after another. But her stories are inter-related, often to the extent where it’s hard to separate the strands. It’s equally hard to fathom the mystery of the paired family members, the "not quite twins" who populate the novel. Perhaps the trope takes off from Partition and the emergence of a twinned India and Pakistan. Does it work? Not quite!
