Gene Wolfe, Pandora by Holly Hollander

Gene Wolfe must have occasional urges to branch out into the young adult market - he seemed to be trying it with The Devil In a Forest, and he tried it again with this one. It's also the most straightforward book of his I've read (not counting Operation Ares), in that it is a mystery story with no supernatural elements (although there's an undercurrent of classical myth, because Wolfe cannot resist infusing every novel he writes with classical myth). And lastly, it seems to be the first book in a prospective series, and I'm kind of disappointed there was never enough interest in this one to make sequels.
