This is a great Justice League of America book. If you want to know more about Kyle Rayner (Earth's second Green Lantern) and how he came to be Green Lantern and Joined the Justice League, you should read this book.
A long time reader of comic books (practically from birth) it is good to see the tradition carried on in paperback. This was kind of fun. An adventure told in first person by the 'latest' (to me anyway) Green Lantern, Hal Rayner.
