Rule 34 of the Internet states, "If it exists, there is porn of it. No exceptions."
(Note about ebook editions: The US Kindle ebook will be available on the day of hardcover publication in the US. There will be a Kindle edition in the UK but there's a hangup between the Orbit and Amazon databases: it should be fixed shortly and I'll update this entry with a link to the UK Kindle edition when I get it. Also note: I'm seeing $15.76 on Amazon.com for the US hardcover, and $12.99 for the Kindle edition. But some folks report seeing $18.61 for the Kindle edition. Amazon are known to do differential pricing — showing different publishers different prices; if you get the silly price complain to Amazon, not me.)
Oh, and I have some book covers for you:
Which do you think is the British (Orbit) cover, and which is the American (Ace) cover?
