The story of the heart is never half-written.

Macy Sorensen has settled into an ambitious, if emotionally languid, routine: working hard as a new pediatrics resident, planning her wedding to an older, financially secure man, holding head down and heart hidden.

But when she meets Elliot Petropoulos - the first and only love of her life - the bubble she created begins to dissolve. Once upon a time, Elliot was Macy's whole world - he grew from her bookworm to the man who helped her open her heart after losing her mother... and broke it the very night he confessed his love to her.

< p>Taking turns, teenagers Elliot and Macy transform from friends into something more, spending weekends and lazy summers together in a house near San Francisco, devouring books, sharing their favorite words and discussing their pains and victories. As adults, they became strangers to each other until they met by chance. Although their memories are clouded by the agony of what happened that night all those years ago, Elliot will understand the truth behind Macy's ten years of silence, and he will have to overcome the past and himself to restore her faith in the possibility of all-consuming love.
