The book is shipping! I got my first copies Friday, and Amazon pre-orders are expected to be delivered tomorrow. It looks and feels great – hefty at nearly 600 pages, but not too fat.
Want a discount? Email me. Cambridge has a code good for 20% off (but maybe with Amazon's price and free shipping, you're as well off ordering there). I look forward to signing copies for anyone who gets one.
I've found a few minor bugs already. I'm still offering $1 per bug reported. I'll start an errata list soon.
And if you'd like to consider the book for a course, the publisher might send you a free examination copy. Let me know if interested.
