The link is https://www.amazon.com/Dmn-Method-Style-2nd-Pracitioners/dp/0982368178.  As I posted recently, the second edition is completely rewritten and updated to DMN 1.2.  The examples are all executable and the book follows closely my updated DMN Method and Style Basics (available now) and Advanced (about a week away) training.  It’s just gone up today, and looking lonely with zero reviewers.  So please, if you like it, post a review on Amazon.
