Misper: Volume 4

When Ryan Kennedy is imprisoned for the murder of a police officer, he knows what he has to do. Keep his mouth shut about who he was working for, keep his head down, and rely on his youth to keep his sentence short. When he gets out, he'll be rewarded.

It asks who deserves to be saved - and whether saving them is even possible...
