I'm doing a reread of the Chronicles of Narnia, and I started with The Silver Chair. It was better than I remembered.
It's a solid adventure story, and I like Jill. I'm not a huge fan of Puddleglum, but I found him less annoying than the first time I read the book.
A few more random thoughts about The Chronicles of Narnia after the cut.
1. I find people who insist you have to read the books in a specific order some of the most annoying people. Read the books in whatever order you like. They're not Harry Potter. It will not ruin the series if you read them in the "wrong" order.
2. My first grade teacher read us The Magician's Nephew and it's been my favorite in the Narnia series ever since.
3. I read two books in the series (Magician's Nephew and The Lion, the Witch and the Wardrobe) as a kid but got stuck on Horse and His Boy. Years later someone pointed out to me that Horse and His Boy is the only book set entirely within Narnia and then I understood why I disliked it so much.
4. I finally finished reading the series while I was living in England when I was ~20.
