Switch: How to Change Things When Change Is Hard - Hardcover - VERY GOOD
What I like is that the book is illustrated without overwhelming the text.
The Power of Moments: Why Certain Moments Have Extraordinary Impact - VERY GOOD
A nice touch is the illustrated author bio at the very end.
Made to Stick: Why Some Ideas Survive and Others Die - Hardcover - VERY GOOD
With this activity book, you can learn about animals while solving puzzles.
