Supergirl Vol. 3: Reign of the Superboys - Hero of Kandor

Caught between a rebellion and a crumbling government, Supergirl must decide what kind of hero Kandor truly needs.

The acclaimed Supergirl series from writer and artist Sophie Campbell continues as Kara Zor-El returns to Krypton’s last surviving city at its darkest hour.

Superboy has come to Midvale with a mission: The bottled city of Kandor is at war, and Kara must abandon the comfort of the suburbs to save the last survivors of Krypton.

The Kandorian youth are in revolt after learning the Science Council has been keeping a shocking secret from them. Unfortunately for our hero, their leader, Black Flame, has Lesla-Lar and her Super-Substance on her side. But the council has its own experiment ready to help Supergirl save their city: a trio of Boy Thunder clones who call themselves Team Thunder! Can Supergirl make peace between the two warring factions before the city destroys itself?
