Fate is a statistics-addict's worst nightmare, which is exactly why Charlotte Rosen is dedicating the last year of her twenties to getting back in the game.

Charlotte, a programmer in Los Angeles, develops an algorithm to connect businesses with social media standouts, but soon realizes her app could be used for personal reasons, too: finding Mr. Right after suddenly becoming a widow five years prior.

No one knows about Charlotte's past, and that's just the way she wants it. But just as she's about to take her previous relationship secret to the grave, a mysterious package arrives on her doorstep. Nothing in her app could have predicted that her late husband's ashes were in the box-or what the untimely delivery will do to her data driven approach to love.

With her world instantly thrown into chaos, Charlotte has no choice but to confront what she's been running from for the past five years: estranged family, fractured friendships, and most of all, her own heart.
