Some people wait their whole lives to find their soul mates. Not Holly and Gerry. No one could imagine Holly and Gerry apart.Until the unthinkable happens. Gerry's death devastates Holly. But as her 30th birthday looms, Gerry comes back to her. He's left her a bundle of notes, each note signed "P.S. I Love You." As the notes are gradually opened, Holly is both cheered up and challenged. Gerry sets out to teach her that life goes on. Life is for living, she realises - but it always helps if there's an angel watching over you.
