The thing about the guess-the-plots is that there are a lot of gems that get missed, since they're not the plot the query is about. This one is from Face-Lift 1222, Kidblog:
Eight-year-old Ricky starts a blog dealing with life at Fontana Elementary school. Tough tests, tough teachers, Tough-Luck Bobby (Maria likes Finn). Meanwhile, mommyblogger Cindy Sharon starts a blog about raising her home-schooled genderneutral child Moon as a vaccine free, gluten free, and religion free vegan. Everything's fine until Ricky and Moon email each other.
I thought this one would be a pretty cool MG novel if the characters were aged up a bit. (Say, from eight to eleven/twelve.) Thing is, realistic fiction is not my forte. So, if the blog readers have any suggestions for a plot I'd be really thankful.
