The internationally bestselling author of “How to Stop Time” presents a dazzling new novel about all the choices that go into a life well lived. Somewhere out beyond the edge of the universe there is a library that contains an infinite number of books, each one the story of another reality. One tells the story of your life as it is, along with another book for the other life you could have lived if you had made a different choice at any point in your life. What if you had the chance to go to the library and see each of these possible lives for yourself? Would any life truly be better? Matt Haig’s enchanting new novel follows one woman’s search within herself as she travels through the Midnight Library.
