Avatar: The Last Airbender: North and South Omnibus

The fifth arc follows Katara and Sokka back to a Southern Water Tribe that’s grown since they left. A proposal to unite the tribes gives Katara and other Southerners sharply different ideas about what progress should look like. This completes the five arcs in Gene Luen Yang’s omnibus boxed set. You can also get this arc on its own in one volume.
