I just read your book so I'd like to say it's awesome :) You explained all these linguistic features so clearly, I learnt so much. The minimalist in me almost had a heart attack when you mentioned Castithan's writing system was created just before a major sound change ("Why would you make it so difficult to learn?!") but it was really cool seeing how you make these languages so naturalistic. It was a funny book too. Any particular reason you hate onions so much?
