Leviathan - Scott Westerfeld, Keith Thompson This book came well recommended, and unlike some of the other "Steampunk" I've tried, this volume lived up to the recommendations. While shelved under "YA," and while they might miss the incipient romance at the heart of the story, Leviathan would be appropriate for middle-grade readers as well. At heart, this is a coming of age story. I do like a good coming of age story.
