Sixteen years after Cecelia Ahern's bestselling phenomenon PS, I Love You captured the hearts of millions, the long-awaited sequel follows Holly as she helps strangers leave their own messages behind for loved ones.

Seven years after her husband's death -- six since she read his final letter -- Holly Kennedy has moved on with her life. When Holly's sister asks her to tell the story of the "PS, I Love You" letters on her podcast -- to revisit the messages Gerry wrote before his death to read after his passing -- she does so reluctantly, not wanting to reopen old wounds.

But after the episode airs, people start reaching out to Holly, and they all have one thing in common: they're terminally ill and want to leave their own missives behind for loved ones. Suddenly, Holly finds herself drawn back into a world she's worked tirelessly to leave behind -- but one that leads her on another incredible, life-affirming journey.

With her trademark blend of romance, humor, and bittersweet life lessons, Postscript is the perfect follow-up to Ahern's beloved first novel.
