Are The Magic Treehouse books in order of difficulty?

Thanks!

not particularly as I recall.

don't think so but there is a website

I don't think so. Ds1 is on about number 11 at the moment having read the first one around this time last year, but I haven't noticed an increase in difficulty over the year.

I don't think so. DD has read a couple and there was no obvious difference in dificulty IIRR.

Thanks, we'll pick and choose then
