Some people wait their whole lives to find their soul mates. But not Holly and Gerry. They were childhood sweethearts - no one could imagine Holly and Gerry without each other. Until the unthinkable happens. Gerry's death devastates Holly. But as her 30th birthday looms Holly discovers that Gerry has left her a bundle of notes, gently guiding her into her new life without him, each signed "P.S., I Love You." With some help from her friends, and her noisy and loving family, Holly finds herself laughing, crying, singing, dancing - and being braver than ever before.
