Green Lantern Corps TPB Volume 02 Alpha War (N52)

When the Alpha Lanterns, the internal police force for the Corps, arrest Green Lantern John Stewart for the murder of a fellow Lantern, it sends shock waves throughout the entire Corps-especially since Stewart refuses to defend himself against the charges. Now, in these tales from issues #8-14 and 0, it's up to Guy Gardner and the rest of the Green Lanterns to break Stewart out and bring down the emotionless Alpha Lanterns.
