The Silver Chair (Chronicles of Narnia Series #6)
As much as I enjoy this book, I'll say the Pevensies have always been my favorite characters in The Chronicles of Narnia, so having a book centered solely on Eustace and Jill doesn't make me LOVE the book in the same way. I did really enjoy the introduction of Jill and it was nice to see Eustace post-Voyage of the Dawn Treader. Also wins points for Puddleglum.
