Not nearly as good as I remember it when I was a kid. Carey's weird manifesto in the middle kinda derailed it for me. Believe what you want but please keep it out of Trek. What do y'all think?
How much more Mary Sue than to have the cover art be based on the author and her RL husband? (at least that's how I heard it)
As for the story itself, I have long thought Carey was among the worst of the novelists, and have yet to read anything of hers that would change my mind.
