Jonna and the Unpossible Monsters Vol. 1 by Chris Samnee

Rainbow has been looking for her younger sister, Jonna, for over a year--since the monsters appeared and their world began to dry up. Going from settlement to settlement, Rainbow asks every survivor she meets: Have you seen my sister?

Then, one day, Jonna's spotted out in the wild: filthy, but strong. Strong enough to knock back a towering monster with one punch. All this time, she's been surviving. On her own. Without Rainbow. Without anyone.

But there are more dangers in the world than monsters, and when the two sisters reunite, they'll discover the secrets of this new and terrifying world firsthand.
