If our life had turned out differently, would it have been better? We do not know. But the one we are given is valuable in itself, that's what Matt Haig's new novel is about. Between life and death there is a library. This is where 35-year-old Nora, a music teacher from Bedford, finds herself when her whole life goes downhill one night. The shelves here go on forever. Each book gives you a chance to live your own, but completely different life. Make different decisions and, most importantly, do not regret what once did not happen. It turns out that if Nora had acted differently at one point or another in her life, she could have become a rock star, an Olympic champion, a glaciologist, a wife and mother, and visited Australia. But would she be happier?
