I've been lightly pimping this book for a while now, but I need to step up my game.

"Drawing Comics" by Scott McCloud is THE definitive book on drawing comics in my opinion. It talks about everything that really goes into making a comic and doesn't just focus on a specific style. It breaks down comics into their core elements and is absolutely fascinating to read.

The book is actually written AS a comic book, meaning it looks more like a comic than a book. However, it really has a TON of information and is great for anyone who would ever want to delve into comics in the slightest way.

It's relatively cheap (under 20$) and has enough stuff in it to keep you occupied for a while. It's not intended as a "how to draw" book, but it does have great exercises in between chapters for those wanting some hands on work as well.

In short - BUY THIS BOOK. Scott McCloud is very respected in the comic book field for a good reason, and this book is nothing short of a comic book bible.
