Description：

At twelve years old, Quinn Lawson discovers the truth: she was switched at birth, and the gambling addict who raised her is not her mother. Her real family has wealth, a beautiful house, and a daughter they already love.

Quinn was never supposed to be the one they brought home.

What follows is a childhood defined by cruelty from the sister who sees her as an intruder, parents who choose comfort over truth, and the slow, grinding work of building a life out of almost nothing. Only the piano — practiced in secret, in empty classrooms after dark — offers her a way forward. And only Cole Harrington, the quiet boy from the military compound next door, stays when everyone else turns away.

A sweeping, emotionally powerful story of injustice, survival, and the love that makes it worth enduring.

*The Longest Love Letter* is about what you build from the wreckage — and the one person who never stopped believing you could.
