 The novel I Am Legend is about Robert Neville. He's a soul survivor after this crazy pandemic hit the world and basically wiped out everybody turning them into essentially vampires. And for some reason he is the only person who's immune to all this stuff. He actually slowly becomes like a makeshift scientist trying to find out why this is happening and how he can maybe try to cure these people. It really kind of scientifically explains what makes someone a vampire which is neat. Neville keeps himself boarded up in his house because at night time these vampires come out and they go looking for him. And the leader of these vampires is his old friend actually Ben Cortman. During the day he hunts these vampires and there's also a woman that he finds running around in a field and he brings her back. Turns out that she's infected too.
