Some SPOILERS
The volume, introduced more background into the Blue Lanterns, the home of the Blue Lantern Corps Power Battery and some of their powers. Jordan struggle to get the Blue Power Ring off throughout the issues to no effect and just doesn't see how the Blue Power of Hope can help him, even going to declining to become a leader of the Blue Lantern Corps. Even though Saint Walker advices him that the only way to take the ring off is by using all the power, draining the ring.
However, when Hal Jordan finds himself in Vega System things do get more interesting as Hal finds the wielder of the Orange Lantern and the battle is pretty good with some unexpected twists.
All in all I liked Agent Orange, a pretty good lead in into Blackest Night
