The final volume of Jason Todd and his problematic team's misadventure is probably the greatest of the trilogy.
It is highly recommended for the reader to have fully read Red Hood & the Outlaw 1 and 2, as 3 is a direct continuation of the series. I can't say much without spoiling the context of the book, but do know that this book contain some of the most twisted and wicked trick of the Joker. It will make your skin crawl to see what he put the bat family through in one of his greatest mayhem yet.
The art style is excellent and consistent, something volume 2 lacked. There are also admirable amount of screen-time for Tim Drake and Damian Wayne (kind of), so the fans of those Robins will be pleased too.
This book is less about the Outlaw, and more about Jason Todd and his inner demon. Something that also made it better than volume 2 (As volume two was heavily leaned towards Starfire.)
