In a small pocket of London, between the houses of Number 77 and Number 79 Eastbourne Road, lies a neglected community garden. It was once a beautiful thing, but now it’s overgrown and neglected. Once a sanctuary, the garden’s gate is now firmly closed. And that’s exactly how Winston at Number 79 likes it --- anything to avoid Bernice, who has moved in next door with her young son. But then a mysterious parcel drops on Winston’s doormat. It contains only a bundle of photographs of the garden in bloom many years ago --- vibrant with flowers, filled with people from every corner of the community. The seed of an idea is planted. Somewhere out there, a secret gardener made a decades-old promise to keep the community’s spirit alive. Now it’s time for The Twilight Garden to come out of hibernation.

Widower Mukesh lives a quiet life after losing his beloved wife. Aleisha is a bright but anxious teenager working at the local library for the summer when she discovers a crumpled-up piece of paper in the back of TO KILL A MOCKINGBIRD. It’s a list of novels that she’s never heard of before. Intrigued, and a little bored with her slow job at the checkout desk, she impulsively decides to read every book on the list, one after the other. As each story gives up its magic, the books transport Aleisha from the painful realities she’s facing at home. When Mukesh arrives at the library, desperate to forge a connection with his bookworm granddaughter, Aleisha passes along the reading list…hoping that it will be a lifeline for him too.
