A stray cat brings together five strangers over the course of one fateful summer in this heartwarming novel about love, found family, and the power of connection. Núria, a single-by-choice barista with a little 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 her volunteering days, she starts finding Post-it notes left by a secret admirer in an area where her feeds her favorite stray—a black cat named Cat. Like most felines, he is both curious and observant, 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?
