The Anne of Green Gables series. Eight books. They're amazing. I have the exact set shown below...I love boxed sets. :)
Many people like the first one (Anne of Green Gables) best, and maybe it is the best, but I tend to prefer some of the others. Anne of Avonlea, the second is fun, and so is Anne of the Island. In each of them, Anne gets into adventures that are laughable to us, if not to her. ;) By the 6th book, they start focusing more on Anne's children and family. The 8th book, Rilla of Ingleside has a sweet romance of her daughter, and some sad parts too, but it's worth the read. Something that I just discovered is that she didn't publish them in order. Rilla came out before Windy Poplars or Ingleside. I am sorry for the people who didn't read them in chronological order like I did! Technically, there's a sequel even to Rilla, which it appears Maud intended to be the ninth book in the series. It's called The Blythes are Quoted and it was only published recently. I haven't read it yet.
Maud Montgomery wrote a lot more books than those eight, though! In 1910, she came out with Kilmeny of the Orchard. Incidentally, I just finished reading this one on Kindle, and adored it. :) You can get a free Kindle copy from gutenberg.org ! :) There should be a review of it coming soon. It was a really sweet romance.
Her next two books were The Story Girl and The Golden Road. The latter is a sequel to the former. Again, reviews of these are coming, hopefully later today, since I read them on the Kindle as well. Check out my reviews for more info.
In 1923, Emily of New Moon came out, soon followed by its sequels, Emily Climbs and Emily's Quest. I own this short series. The second is my favorite, and the third I really didn't like very much.
Montgomery wrote a variety of short story collections, including Chronicles of Avonlea and Further Chronicles of Avonlea, both of which I recently enjoyed.
I still have not listed nearly all of her works. She came out with many other short story collections herself, and there were some that were assembled and published after her death.
She also had some other chapter books, such as the Pat series (Pat of Silver Bush, Mistress Pat), The Blue Castle, and Magic for Marigold, along with others. Those are all ones I hope to read soon. :)
Before you go...which of these books that I've mentioned here are you familiar with? Have you read some I haven't? Do you want to?
