Just two months after the launch of the first Awkward Family Photos book, bloggers Mike Bender and Doug Chernack have sold two more books from the popular site to Three Rivers Press.

The Crown Publishing Group imprint has scheduled Awkward Family Pet Photos for fall 2011 and an untitled third book for a later release date. Rebecca Oliver of WME negotiated the deal with senior editor Suzanne O’Neill. According to the release, Awkward Family Photos spent 10 weeks on the New York Times‘ bestseller list.

Here’s more about the next title: “Awkward Family Pet Photos is based on a spin-off site Bender and Chernack have just launched of the same name. It currently gets over 4 million impressions per month. The new book will include the most outrageous submissions from the site, along with many never-before-seen photos. The book will showcase the hilarious, and sometimes disturbing, bonds families and owners have with their pets.”
