Not only is it one of my favorite books, but John Austin's Mini Weapons of Mass Destruction also makes a great gift for kids or adults who refuse to grow up. And since I fall into that latter category, I'm pretty excited to see he's now got a sequel that lets you re-appropriate your office supplies into thirty new spy weapons and surveillance tools.
