Lex Luthor: Man of Steel
No other book treads so fearlessly into the mind of Superman's greatest foe, Lex Luthor. Told through his eyes, we see Superman as a mysterious demigod from an alien planet with so little respect for humanity that he feels the entire species needs a micro-managing babysitter. Luthor believes that the only way for the human race to survive is to find a way to protect and govern itself, which means stopping Superman once and for all. Not only is the novel a gripping adventure, it's a smart meditation on how the definition of heroism depends on one's perspective.
