On Friday I went with Sam Eades, my lovely publicist at Headline, to Clays printers in Bungay, to see Every Vow You Break roll off the presses. I had been told by David Headley at Goldsboro Books and S J Watson that it was an astounding day out (‘like Charlie and the Chocolate Factory for book nerds’), and that the sandwiches were very good. They were right on all counts.

After those remarkable sandwiches at Cambridge House, a beautiful Georgian building where the company started and which they now use for hospitality, We were shown around the massive factory by the lovely Vicky Ellis and Phil and Steve, having a peek at every single part of the process.

Standing in the middle of a factory full of conveyor belts piled up with my new novel has to be one of the top experiences of my life. If I say how close I was to wanting to breast feed my warm, fresh, book, you’ll understand where it ranks for me.

Here, in the spirit of a geography field trip, is my photo essay. Unlike when they were printing the first editions of Harry Potter, when even mobile phones were confiscated at reception, they now allow cameras in.

So hard hats and hi-viz jackets off to all at Clays, and thank you for a day I will always remember.
