Query: Worst Micro Book EVER

I used to like Econ before this book. This book is confusing, hard to follow, and torturous to read. While reading it, I find myself taking a well-deserved nap every 15 minutes. It seems like the author deliberately tries to explain things in the most confusing and driest way possible. Also, there are too many equations throughout - many of which hurt your brain in the way they are explained. This is the first time I've written an online review of any sort, but I felt like I had to perform a public service and let you know before you buy.
