She also shared a video announcing the exciting news.

\"Postscript\" will follow Holly Kennedy once again, picking up years after she lost her husband, Gerry, and found his set of letters that brought her on a journey of discovery and love.

Ahern provided a complete description of \"Postscript\" on her website:

\"When Holly Kennedy is approached by a group calling themselves the PS, I Love You Club, her safe existence is turned on its head. Inspired by hearing about her late husband Gerry’s letters, the club wants Holly to help them with their own parting messages for their loved ones to discover after they’re gone. Holly is sure of one thing — no way is she being dragged back to the grief she has left behind. It’s taken seven years to reinvent herself, and she’s ready to move on with her life. But Holly comes to realize that when you love someone, there’s always one more thing to say.\"

She also described the novel as a \"deeply emotional project,\" in a statement on her website.

\"Postscript is the PS to my PS and while it is a sequel, it is also a story that stands alone about living a purposeful life in the face of illness, grief and loss. I hope that new readers and PS, I Love You fans alike will embrace Holly’s new journey.\"

\"PS, I love you\" was adapted into a tremendously successful box office hit starring Gerard Butler and Hilary Swank, which was released in 2007. The film made almost $157 million worldwide.

Here's to hoping this upcoming novel is adapted into a sequel to the heartbreaking film!
