I posted a bonus excerpt yesterday as a reward for the folks who helped me raise $750 for Extra Life, a gamer-charity benefiting Children's Miracle Network. Today you can watch the D&D Extra Life team playing (and win a variety of prizes) at http://www.twitch.tv/wotc_dnd (I'm playing from 4pm-8pm PST).
The excerpt is here: http://slushlush.com/2013/11/the-adversary-bonus-excerpt/
(Extra-life.org is currently under a DDoS attack (because some people are terrible 
), but they are working hard to get the site accessible again. If you'd like to donate, watch here or on the Twitch channel, and we'll let you know if it's cleared up)
EDIT: Huzzah! The second I posted this, Extra Life reported their site is back up! It may not be immediately accessible, but it will be soon. You can donate to a variety of teams...but I think you should pick mine.
