From Matt Haig's Twitter: 'It is about a library between life and death where a woman gets to try all her other lives she could have lived. It will be out next September if I actually finish it.

Nora feels swamped by all the bad choices she has made in life and attempts to take her own life. Then, when given the chance to see all the ways her life could have been different, she must finally work out the answer to the ultimate question: what is the best way to live?.'
