I've mentioned before that I'm a fan of John Verdon's books:
Think of a Number (Dave Gurney, No.1)
Shut Your Eyes Tight (Dave Gurney, No. 2)
I'm VERY excited that John's going to write a guest blog for us! His third book is coming out this month, and his guest blog will appear on Monday, July 23. There will be excerpts and more, so mark your calendar!
His website is here: http://www.johnverdon.net/pages/index.php
And his Facebook page is here: https://www.facebook.com/authorjohnverdon
