I was amused when a book I was reading on the train yesterday mentioned Mumsnet - the protagonist had apparently spent a lot of time on Mumsnet and, in the story, was on there again looking for advice about her son's problems. The novel was 'Don't tell teacher' by Suzy K Quinn.
I wondered what other novels namecheck Mumsnet and if any writers on here have ever included Mumsnet in their books (Suzy K Quinn, if you are on here IRL, your book kept me sane by absorbing me on a packed and delayed train, so thank you
).
If you've read (or written) a book that mentions Mumsnet, what was the book and why did MN come into it?
