Very good. My favorite so far in the series. Wrestles with the stuff I like (life as journey vs destination, being lost, the road rising to meet you, etc) while tackling bigger ideas about valuing life and death equally. PLUS there was dragons and spells and strange & distant lands, so.
Also (POSSIBLE SPOILER) it has my favorite favorite kind of ending, which is where the story ends one way, but there's a 2nd, oppositional ending layered on top of it (see films like "The Good Girl" and "25th Hour" for examples of this).
