Set against the backdrop of 1970s New York City, 'When You Reach Me' follows the life of young Miranda as she navigates friendship, family, and the bewildering appearance of cryptic notes that challenge her understanding of time itself. After her best friend Sal is inexplicably punched by a stranger, they drift apart—only for Miranda to be pulled into a mysterious puzzle. Whoever leaves the notes possesses knowledge of the future and insists that Miranda must pen a story of truth to prevent an ominous death. As the notes predict events with unnerving accuracy, Miranda's belief in the impossible begins to waver. It's a journey that intertwines the themes from 'A Wrinkle in Time', Miranda's favorite book, into her very reality, culminating in a narrative ripe with intrigue and a testament to the enduring power of friendship.
