Girl unknown - Karen Perry

When Zoe Barry walks into Professor David Connolly's office and announces that she is his daughter, he is left reeling. Suddenly his family - imperfect, flawed, but working - is trying to find space for someone new.

But Zoe's stories don't quite add up and lies become indistinguishable from truths. The family struggle to make sense of whether she is a sister, a daughter, a friend, an enemy. But no one could have expected where it all might end.

Because they have let into their home a girl that they do not know. And now everything they have built has begun to violently, determinedly, break apart.
