The second psychological thriller from S. J. Watson, author of the international bestseller Before I Go to Sleep.
Can you really know another person? And how far would you go to find out the truth about them?
When Julia learns that her sister has been killed, she’ll do whatever it takes to get to the bottom of things. Even if it means jeopardising her relationship with her husband and risking the safety of her boy. Getting involved with a stranger online. Losing control. Perhaps losing everything.
A tense, unrelenting novel set in Paris and London, Second Life is about the double lives people lead-and the dark places where they can end up.
