I keep meaning to read Sean Stewart; the only thing I know of him (assuming it's the same guy, of course, but I think it is) is that he was the head writer for the online murder mystery "game" that was part of the marketing campaign for A.I., which turned out to be about a thousand times cooler (and better-written) than the movie itself was.

For your category of "likes animals", naturally, I must again pimp Watership Down, which you STILL haven't read, have you? I shake an admonitory finger at you!
