I tore through the Anne series last week! I agree with you; I always wished there was a book from Gilbert's POV. I would've loved to see his perspective more in general; he seemed like he had such a sense of humor.

Miss Cornelia is fantastic. During and after I finished the series, occasionally her pet phrases would pop up into my head (usually "Isn't that just like a _____") and her first meeting with Anne and Gilbert was lovely.

I don't typically like books like these (give me explosions and magical explosions, please) but Anne of Green Gables + sequels just had this charm to them.
