The "Diary of a Wimpy Kid" children's book series has legions of fans around the world. Now, this fall, a new book will be released to add to the six books that have sold more than 75 million copies worldwide.  

The inaugural book was published in 2007 and quickly became a New York Times best seller, ultimately securing the #1 spot.  The books that followed did equally well.

Jeff Kinney, the author behind "Wimpy Kid" came up with the idea while working as a cartoonist at his college newspaper. After graduating, he had little success in getting his comic strip syndicated so he started posting his cartoons online on Funbrain.com. The cartoons were posted in the form of a daily blog and eventually, six years later, they were published in book form.

According to Publishers Weekly the next book, "The Third Wheel" will go on sale on November 13.

"Writing The Third Wheel has been a lot of fun because there's so much humor to be mined in the world of middle school romance," said author Jeff Kinney in a statement. "When the dust settles at the end of the seventh book, the Wimpy universe will be changed in a way that will surprise fans of the series."
