I'm glad you liked it, Wednesday
If you have read anything like it (not YA), please share.
The premise is taken almost entirely from Snow Crash, including the Babel connection and ancient 'basewords'. Lexicon develops the idea further imho and makes a great read in itself, but Snow Crash has a much better developed mythological angle. You end up believing that is exactly what happened in Sumerian times & worshipping Neal Stephenson because he must be a minor God to think up such a story.
