I can't add much to the actual reviews here: lots of useful, interesting and perceptive comments about the entire 'Anne of Green Gables' series have been submitted already, at both Amazon.co.uk and American Amazon.com.
However, I'm not as familiar with the books as I was during my library ticket prime some three decades ago, and I needed to piece together a reading order now that I'm re-discovering them with younger members of the family.
Pinning this order down is surprisingly difficult - the 'Anne' books were not written in chronological order, and there are two books of short stories that are set in Avonlea, but not about Anne Shirley. Also, 'Anne of Windy Poplars' and 'Anne of Windy Willows' are one and the same novel; the latter title was used in the UK upon first publication, but now appears to be used only in the Penguin paperback edition. There are two 'sequels' that are actually about Anne's children, and then several more books by L. M. Montgomery that sound similar but are not part of the `Anne' series.
So, in the hope other customers find this useful, here's the reading order for the series, at least as far as I can make it out:
1)'Anne of Green Gables'
2)'Anne of Avonlea'
*2.5) Short stories 'Chronicles of Avonlea'
3)'Anne of the Island'
4)'Anne of Windy Poplars' (also known as 'Anne of Windy Willows')
5)'Anne's House of Dreams'
6)'Anne of Ingleside'
7)'Rainbow Valley' (a sequel, in which Anne is an adult background character, with her daughter Rilla taking up the juvenile protagonist role)
*7.5) Short stories 'Further Chronicles of Avonlea'
8)'Rilla of Ingleside'(another sequel primarily featuring Rilla, obviously!)
There are also at least two further sequels and short story compilations which opportunistic editors and publishers have assembled in recent years from previously discarded manuscripts. I haven't read these, and probably won't - L.M. Montgomery had a fifty year writing career, and I'm reluctant to read material that she herself rejected lest it diminishes my huge fondness for her works.
Now, having sorted out the running order, here are a few cautions to avoid disappointment when you decide to read the whole series:
Firstly, at least at the time of writing, not all the books in the series are available on Kindle. I downloaded all those that are, but had to go back and fill in the gaps with hard copies; now we have an incomplete set of paperbacks and an incomplete set on Kindle, so not ideal.
Secondly, as seems often to be the case with Kindle editions, there are a surprising number of typos. This is confusing when L.M. Montgomery has certain characters employ Prince Edward Island dialect, and you're not sure whether the eccentric vocabulary is intentional, or a misprint. A few are so key that they actually affect comprehension.
Finally, some - but not all - of the Kindle editions use American spellings. This didn't bother me, but if you're buying these books for a child still learning to be confident in their reading, I'd strongly recommend you stick to the actual books rather than the Kindle versions, despite the temptations of money-saving and convenience.
Individually, not all the books merit five stars; some are better than others, and 'Anne of Ingleside' is probably my favourite. The Kindle editions don't do justice to the books as yet, and need further revision. But overall, I loved these books, it was great fun to return to them, and you don't need children in the house to enjoy them all over again.
