My natural curiosity led me to check out the Wizards of the Coast website to see if they’d posted my bio yet. It turns out they’re quicker than I thought. You can see the bio here.
Better yet, the official product page is here. I was told the book would be released in August, but it says June here, so who am I to argue?
It’s also available for preordering at Amazon.com. Although Amazon lists the book at 256 pages, Wizards claims that it’s 192. I’d go with Wizards on this one. Either way, I encourage you to preorder it through your local game store first if you can.
