I've read an advance copy of The Serpent Sea, and it's just as amazing. Add to that characters who stick with you and whose motivations you really care about, and this is a real winner. (Except I'd get eaten in 5 minutes.) Moon's people are one of the most intelligently-constructed fantasy races I've seen in awhile - science fictionally so, though the story manages to retain the wonder and magic of fantasy. This is a rich, complex, plausibly exotic fantasy world like nothing on earth, described so vividly that I'd love to go visit it. But that isn't this story's greatest asset the worldbuilding is. Then on top of that, Moon has baggage from a prior encounter with enemy shapeshifters, which comes back to haunt him with a vengeance. So suffice it to say Moon's homecoming is.

He learns that a) he's a member of an especially coveted subgroup within his people, and b) he is simultaneously a member of an especially reviled subgroup. Moon finds his people early in the book, and it's not a happy experience for him. But where other stories end (last of his kind finds a place) is pretty much where this story started, nearly ended, then started again. It didn't really look all that interesting to me based on the jacket copy - stock story, possible last of his kind looking for a place to belong, etc.
