From the New York Times bestselling author of Tokyo Ever After comes a laugh-out-loud funny and deeply moving rom-com about a girl who starts receiving letters from the love of her life—writing to her from years in the future.

What if your true love could write to you from the future?

Seventeen-year-old Emma Nakamura-Thatcher doesn’t believe in love, not after her parents’ bitter divorce. So when she attends the festival of Tanabata, her wish is simple: proof that love is real and can last.

Emma thinks little of her wish…until she finds a note from someone claiming to be her greatest love writing to her from the future. It has to be a prank, right? But as the notes pour in, each revealing secrets only she knows, Emma is forced to accept the impossible: This is really happening. Someone is actually reaching out to her from across time.

But who? Ezra, the musical prodigy who makes her pulse race? Theo, the literal boy next door who’s known her since childhood? Or Colin, the overly confident, overly handsome, overly rich kid she meets while cleaning his mega-mansion?

As Emma races to uncover the identity of the letter writer, she’ll discover that love is more than real—it’s the most powerful force in the universe. And it’s been waiting for her all along.
