Thanks to Louisa for this recommendation!!
I’ve put up TWO reading order guides for this one on this page (because the reading order has been somewhat debated). The first listed is as per the author as she has them listed on her website (and as per her confirmed emails to me, that you’ll see below in the comments). Some readers agree with this version. However many readers and fans of the series have stated her reading order to be confusing and have relisted them in the order they believe they *should* be read. Therefore, below the author’s reading order, I have listed the “readers” reading order. See the comments below (regarding both “sides” of these reading orders), and choose which version you think is best for you!
