Green Lantern: Rage of the Red Lanterns. By Geoff Johns

Now that the Sinestro Corps War is over, and we have a established all the facts about the emotional color spectrum, on to introducing all of the emotional color corps/factions to lead up to the Blackest Night.   We know that the Green Lantern Corps is built around the color green that is the power of will.  The Sinestro Corps is built around the color yellow that is the power of fear.  And the Star Sapphire Corps is built around the color violet that is the power of love. (Que Huey Lewis and the News)  We are now introduced to two more factions is the color spectrum.  We have the Red Lantern Corps that is built around the color red that is the power of rage, and we have the Blue Lantern Corps that is build around the color blue that is the power of hope.  The Red Lantern Corps is started by Atrocitus, the same guy who killed Abin Sur that gave Hal Jordan his ring.  While building up hate and rage while being imprisoned on Ysmault, he was able to tap into the red spectrum to craft a red power battery and thus rings.  The Blue Lantern Corps I actually found pretty cool.  The Blue Lantern Corps were founded by the two expelled Guardians of the Universe, Ganthet and Sayd. They were able to create a blue power ring out of their mutual hope for the future.  The thing that I found most interesting about them is that though they are a separate corp, they were made to aid and assist other emotional spectrum ring holders, not replace them.  Our first run it with them, they help Hal Jordan.  Being two X-Guardians, and still caring for the Green Lantern Corp which they helped start, the Blue Lanterns really are the support forces for the front line Green Lanterns.  Towards the end of this book, we are given hints about the orange spectrum and we will find out more in the next book. (Green Lantern: Agent Orange) We do already know that orange is the power of avarice, also known as greed, and that indigo is the power of compassion.  I can't remember if we have been properly introduced to the indigo color and those who wield it, but maybe we will find out in the next book?
During the Sinestro Corps Wars, after Ganthet and Sayd are expelled from the Guardians of the Universe, the Guardians make changes to the Book of Oa.  They wrote in 10 new laws. We already know that lethal force is authorized against the Sinestro Corps.  But in this book we find out that the second new law is that lethal force is authorized against all enemies of the Green Lantern Corps.  I'm not sure why they would have two laws that basically state the same thing.  Probably more of a writers issue.  They probably haven't even figured out what all the new 10 laws will be.  Anyways, most of this book was slow but got a little better towards the end.  I wouldn't pick this one up unless you are wanting to complete the series up to the Blackest Night.  Other then the introductions to the two new Corps and the revelation of the second new law, there didn't seem to be anything that was earth shattering.
