Title: Yes, Logic is made easy
Review: This book achieved its goal- it made logic easy.. because it does not have much to say. One won't have trouble digesting such little material.I think this book is for students who needs basic logic 101. It doesn't cover a lot really.If you want your money's worth, there are some good blogs on the internet(they are free). Just Google.
