The Manual of Aeronautics by Scott Westerfeld and Keith Thompson: The alternate-WWI, steampunk world of Leviathan, Behemoth, and Goliath required a surprising amount of pre-work, describing all the technology and creatures and uniforms so the illustrations of the novels would match Westerfeld’s vision. This book contains a small sampling of those designs, from detailed floor plans of airships to Latin names for fabricated beasties to portraits of some of our favorite characters. It was a very fast read, but I loved the full color drawings. The pictures really helped bring the books to life, and this slim volume only enhances that experience. Recommended for fans of the series, but not until after you’ve finished reading it.
