What a great read!! I could not put this book down; read the whole thing in a day. "After–Part 1" is an incredibly well-written story of the world after an unknown (yet) event caused humans to lose their mind and act zombie-like. The "monsters" aren't undead; they're just people who are infected with a disease and just happen to feel the need to eat humans. Ali is an impressive heroine with a special trait: she was bitten by one of the monsters but did not turn into one herself, like everyone else did. Because of that, she is able to survive on her own, in ways that the few remaining uninfected humans cannot. However, after wandering by herself for a while, living in relative safety, she decides to go looking for answers.
