The Lost Immune (The Walking Dead/Carl Grimes)

Fourth Book! Please go read my other three before starting this one!

Casey can feel herself growing weaker as her memories slowly fade back in. And she's afraid her immunity is weakening as she goes on. She's heartbroken, embarrassed, infuriated. She feels as if the world isn't the same. All these years she has been able to get through it, but now it's just hell.

As if things couldn't get worse, she knows it always will. The Wolves find their way into the walls. Sure, it's easily taken care of; but it's the aftermath she worries about. Something bad is going to happen. It starts with the walls caving in. And it all ends with one man.

So what happens if the Immune isn't immune anymore? Will she burn along with everything else, or will she save the ones she loves?
