I Am Legend

A book on morality, shades of grey, and what it means to be the last man in a world full of vampires. This book had it all, and the crispness of the book did it justice.
I have a very strong feeling that this is one of those books that will look as if the backstory, and some additional expounding of details would make it better, but making the book more realistic, so to speak, would be just pointless filler getting in way of the plot.
Would recommend wholeheartedly.
