The plot is pretty fascinating with various plot twists that I wouldn't have thought of. The book has a good moral as well: you shouldn't live out your dream - magic doesn't solve problems, and even a so-seeming paradise like Fillory can be dangerous as hell. I'm really absorbed by the story. The only thing disappointed me, however, was that I would expect a clearer explanation about what happened to Eliot and Janet (as well as Josh, Richard, and Penny) and how they had met Julia.
