It's set to be called 'Postscript'

Fifteen years after Cecelia Ahern's breakout debut novel 'P.S. I Love You', the author has today announced a sequel is on the way, and soon.

Entitled 'Postscript', it will revisit Holly Kennedy, seven years after her husband’s death.

The official synopsis reads: "When Holly is approached by a group calling themselves the 'P.S. 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 realise that when you love someone, there’s always one more thing to say…"

We can already tell we'll need the tissues on hand for this one.

Ahern said: "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."

'P.S I Love You' was adapted into a Hollywood movie starring Hilary Swank and Gerard Butler in 2007. The book itself sold 1.14 million copies, reached number one in Ireland and the UK, as well as becoming a New York Times bestseller.

Publishing director Lynne Drew, who first acquired Ahern in 2003, said: "It was unforgettable to watch the story of Holly and Gerry capture millions of hearts on page and screen, and to see a young writer take the world by storm, and I know that this thoughtful, deeply emotional sequel will capture hearts all over again. I can’t wait for people to discover 'Postscript'."

'Postscript' arrives on shelves on September 19th, 2019.
