OK, for my opinion on these special editions and the sudden change in Amy / the storyline etc.
Good Stuff: Well, actually, I think it's quite exciting. It's making me really curious. The books are very interesting in my opinion.
Bad Stuff: Yeah, Amy has changed and Ty has changed and I wish they were together! They're made for eachother!
But I am still determined they will get back together. I mean, it would be cruelty if they didn't in the end. They have such a history and everything. I still believe it's going to have a happy ending so I'm going to keep on reading!

But I'm confused about the order... Is book 21 where she decides to go to college? Then what is the first Special Edition?

I've read Beyond the Horizon, I don't know where that comes.. Where does A Winter's Gift fit in and where does a summer to remember fit in??
