Although the exact number of people who have bought all three "Leah" books is unknown, of course, this photo is the first one I have been sent with someone holding all three books in one shot - and all for non-uniform day to celebrate World Book Day 2017.
I'm reliably informed that 9 year old Izzy, "has decided they will be presents for her footballing friends next birthdays!"
"She really does love the books and started reading from number one. She said she wants to think of ideas for the next one!"
I now know where to turn then if I get writer's block.
