Under the guidance of a version of her old school librarian Mrs. Elm, Nora begins trying on alternate lives, including the countryside pub she might have shared with her ex-fiancé Dan and the life in Australia she might have lived with her best friend Izzy. A terrifying encounter with a polar bear in Svalbard becomes the pivotal moment Nora realizes she desperately wants to live, a conviction deepened by a scientist named Hugo who explains the quantum mechanics behind their shared experience. After discovering heartbreak in the rock star life and profound love in a life with a doctor named Ash, the Midnight Library itself begins to collapse, forcing Nora to make the ultimate choice to survive.

After exploring a gentle life with a kind boyfriend named Dylan and then drifting through dozens of lives until she loses her sense of self, Nora accepts she must return home.

The critical turning points accumulate rapidly: Nora discovers her brother ignored her during his visit, loses her last sense of usefulness with an elderly neighbor, and then confronts a Book of Regrets that holds every path she failed to take. Choosing the swimmer life reveals how deeply her father's approval shaped her choices, while a sobering reflection aboard the Svalbard research vessel leads Nora to forgive her parents for passing down their own sense of failure. A disappointing night with the scientist Hugo clarifies that she craves genuine connection over endless exploration, and Mrs. Elm's challenge — that Nora has only ever been living other people's dreams — pushes her to finally choose a life for herself. The life with Ash and their daughter Molly nearly convinces Nora to stay forever, but discovering Mrs. Elm's death in that version and witnessing Leo's downfall remind her that her real life holds irreplaceable meaning. Ultimately, a single phone call from Doreen confirming Leo's lessons can restart shows Nora that her presence in the world matters in ways she never imagined.
