Núria, a single-by-choice barista with a resentment for the "crazy cat lady" label, is a member of The Meow-Yorkers, a group in Brooklyn who takes care of the neighborhood’s stray cats. On one of her volunteering days, she starts finding Post-It notes from a secret admirer at the spot where her favorite stray lives—a black cat named Cat. Like most cats, he is rather curious and sly, so of course he knows who the notes are from. Núria, however, is clueless.

Are the notes from Collin, a bestselling author and self-professed hermit with a weakness for good coffee? Are they from Lily, a fresh-out-of-high school Georgia native searching for her long-lost half-sister? Are they from Omar, the beloved neighborhood mailman going through an early mid-life crisis? Or are they from Bong, the grieving widower who owns Núria’s favorite bodega? When Cat suddenly falls ill, these five strangers find themselves bonded in their desire to care for him and discover that chance encounters can lead to the meaningful connections they've been searching for.
