It is funny how some people act insulted because the "Incredibly Easy" series books have "cartoons" in them; but, I think this is a wonderful book that explains things very very well. Getting a thorough grasp of learning critical concepts is very important when you are dealing with human lives! Who cares about the cartoons, besides the cartoons have "get to the point" information reminders. Every time I opened and studied from this book, I feel like a hero because I learn something every time. This book is hard for me to close because I find it so interesting, and fascinating to learn this stuff. I would highly recommend this book to anyone taking ACLS for the first time, or to review.
