Some people wait their whole lives to find their soul mates. But not Holly and Gerry. Childhood sweethearts,no one could imagine them without each other.
Until the unthinkable happens. Gerry's death devastates Holly. But Gerry has left her a bundle of notes, one for each of the months after his death, guiding Holly into her new life, each note signed 'PS, I Love You'.
As the notes are gradually opened, the man who knows Holly better than anyone sets out to teach her that life goes on. 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.
Life is for living, she realises – but it always helps if there's an angel watching over you.
