A deeply moving, wildly uplifting tale of two strangers with nothing to lose and an unlikely friendship that will grab hold of your heart and never let go.

Annie's heart can't be broken - or so she thinks. After a series of tragic events tore a hole through the perfect life she'd built, there's nothing left to break. Jaded and alone, she's been sleepwalking through life, with a boring job, an irritating roommate, and a serious binge-watching addiction. But she's okay with that - if you've lost everything, you've got nothing to lose, right?

Polly is everything Annie doesn't need in her life - or so she thinks. But Polly is determined to finally wake Annie up to life. Because if having a terminal illness has taught Polly anything, it's that time is short. Too short to waste a single day, which is precisely why she wants Annie to join her on a mission.

One hundred days. One hundred happy things. Annie's convinced it's impossible, but so is saying no to Polly. Now Annie's doing things, and saying things, and feeling things she hasn't felt in a very long while - if ever. Polly's convinced dancing in fountains and riding on roller coasters could heal Annie's shattered heart. But how can she possibly find happiness when letting people in means opening herself to more heartache?
