The Midnight Library

Nora Seed, having lost her job, been rejected from a piano-teaching gig, learned her cat Voltaire has died, and concluded her life has no value, attempts to end her life with an overdose. Instead of dying outright, she finds herself suspended between life and death in an endless library where every book is a version of her life that would have unfolded had she made a different choice at some point. The library is run by Mrs. Elm, a kindly, almost supernatural figure modeled on a real school librarian who was gentle with Nora as a teenager.

Mrs. Elm explains the rules: Nora can open any book and step fully into that alternate life, staying there for as long as it remains genuinely satisfying to her; the moment she becomes unhappy or the life becomes untenable, she is pulled back into the library to try again. Nora samples many lives — an Olympic-level swimmer, a rock musician touring with a band she'd formed with her brother Joe, a glaciologist doing fieldwork in the Arctic, a wife running a country pub with her ex-fiancé Dan, and others. Each life reveals both appealing and painful truths: in the music-career life she discovers that Joe, who is merely estranged from her in her root life, actually died of a drug overdose in that reality; in the pub life, her marriage to Dan is unhappy and he has become an alcoholic. Along the way she meets Hugo, another person who is likewise moving between versions of his own life through a similar library (his takes the shape of a video rental store); Hugo warns her that indefinitely sliding between lives without ever committing is itself a trap, and he ultimately chooses to keep sliding rather than settle into any one existence.

The turning point comes in a life where Nora became a doctor and settled down with a man named Ash, with whom she has a young daughter. This life initially seems close to ideal, but a sudden medical emergency involving her daughter forces Nora, in her role as a doctor and as a mother, to fight to save her. The intensity of this crisis awakens in her a fierce, unambiguous desire simply to live — not to find a flawless alternate life, but to embrace life itself, imperfections included. As she reaches this realization, the library itself begins to destabilize and collapse around her, and Mrs. Elm tells her that the library only exists while she remains undecided between living and dying; having finally chosen life, the library can no longer hold.

Nora is pulled back into her own body in her original reality, in the moments after her overdose, and survives because she is found and gets help in time. The novel closes with her waking in the hospital and beginning to actively rebuild her actual life: she resolves to reach out to and reconcile with her brother Joe, to reconnect with her old friend Izzy, and to follow up with Ash, whom she had run into shortly before her suicide attempt in the ordinary world. Rather than resolving into any single, tidy 'best' life, the ending is deliberately open and hopeful, with Nora choosing to stay alive and see what her one real, uncertain life can become.
