P. S. I love you
Deeply distraught, Holly withdraws from her family and friends out of grief until her mother calls her informing her of a package addressed to her. Within the package are ten envelopes, one for each month after Gerry died, containing messages from him, all ending with "P.S. I Love You". As the months pass, each new message fills her with encouragement and sends her on a new adventure. With Gerry's words as her guide, Holly slowly embarks on a journey of rediscovery.
