The first and most terrifying monster in English literature, from the great early epic Beowulf, tells his own side of the story in this frequently banned book. This classic and much lauded retelling of Beowulf follows the monster Grendel as he learns about humans and fights the war at the center of the Anglo Saxon classic epic. This is the book William Gass called "one of the finest of our contemporary fictions."
Edit: oh, and since I don't think anyone else has mentioned them yet ... Riddley Walker by Russell Hoban, and Grendel by John Gardner. Their impact on me was less specific so harder to explain, but they're great books that get mentioned on HN now and then. Another one that kind of blew my mind is The Infernal Desire Machines of Dr. Hoffmann by Angela Carter.
It is the story of Beowulf, told from the monster's point of view. It underscores the constant internal struggle between nihilistic despair and finding meaning in life (for yourself and others). It strikes a chord with Ozymandias[0].
It is primarily responsible for me abandoning my strong Catholic upbringing (and, ironically, despite John Gardner himself being a Christian).
