Also,

For those scared off by my scary skull-and-crossbones cover on the Secret Principles of Immortality, the cover is undergoing a change, and now will feature a peach color with a phoenix. I hope that remedies the situation. I originally chose the skull-and-crossbones thinking that I needed to fit the 'don't judge a book by it's cover' paradigm (many books try to fit that model, but in this case it was a little inappropriate). And by the way, the phoenix is not a sign of the Luftwaffe, it is an alchemical symbol which may or may not originate from Germany.
