You invited her in. That was your first mistake. Jules and Scott are a young couple living on the outskirts of London.

When the charming and charismatic Orla sweeps into their lives, inviting her to house-share seems like the answer to all their problems: she needs a home, they could do with the money. But once Orla moves in, Jules starts to feel uncomfortable. Whatever the occasion, Orla has to be centre-stage.

Every social occasion, every outing, every get-together is dominated by her and her daily dramas. But on closer inspection, Orla's stories just don't add up. And Jules starts to suspect that their dream housemate might be about to turn their lives into a nightmare.

A tense new psychological thriller from the author of The Perfect Guest.
