The books go by quickly and have plenty of action. Narrator is outstanding as always, bringing the story to life. However, I have to be honest. In an apocalypse, no one is going to listen to or take orders from an 18 year old girl. Especially former marines. Around book four I was getting pretty tired of overbearing Maddie and her constant whining, complaining, fist clenching and doing things her own way instead of sticking to the plan. Unfortunately for me, she was one of the main characters.

Other than that, 7 books for one credit is pretty awesome and they were actually quite good.
