Writer's Digest Books World Building (Science Fiction Writing)

Another in Ben Bova's series on Science Fiction Writing, here geologist and SF scribe Stephen Gillett helps you construct star systems and planets from the atoms up. While it may take you a little more than the proverbial seven days (well, six with rest), when you're done, your knowledge of gravity, weather patterns, cosmic mass and stellar patterns--in this universe--will be greatly enhanced.
This book is designed to give science fiction writers the solid grounding they need in real science to make their fictions read like fact. World Building is a blueprint in words, calculations, tables and diagrams to help writers transport readers from one world to another.
