Between life and death there is a library. Up until now, Nora Seed's life has been full of misery and regret. She feels she has let everyone down, including herself. But things are about to change. When she finds herself in the Midnight Library, she has a chance to make things right. The books in the Midnight Library enable Nora to live as if she had done things differ-ently. Each one contains a different life, a possible world in which she made different choices that played out in an infinite number of ways, affecting everyone she knew as well as many people she never met. With the help of an old friend, she can now undo every decision she regrets as she tries to work out her perfect life. But things aren't always what she imagined they'd be and soon her choices place the library and herself in extreme danger. Before time runs out, she must answer the ultimate question: What is the best way to live?
