Critical Hit, Volume 1

Sarah and Jeanette love animals with a vengeance. Under cover of darkness, they don ski-masks and wield sledgehammers, rescuing abused animals from dog-fighting rings, illegal testing labs, and other abusers.

When they wreak havoc on a rogue gang of hunters, though, the girls find themselves in over their heads. The gang they've stumbled onto aren't hunters - they're serial killers. And soon the liberators become the prey!
