Deep down, Annie Hebden is still mourning the terrible loss that tore a hole through the perfect existence she had once taken for granted --- and hiding away is safer than remembering what used to be. Until she meets the eccentric Polly Leonard, who is determined to finally wake Annie up to life. The mission: One hundred days. One hundred new ways to be happy. Annie will slowly begin to realize that maybe, just maybe, there's still joy to be found in the world. But then it becomes clear that Polly is about to need her new friend more than ever…and Annie will have to decide once and for all whether letting others in is a risk worth taking.
