If you were captivated by Grendel's introspective, questioning perspective and his alienation from the world of men, you'll appreciate Meursault in The Outsider. Both protagonists grapple with meaninglessness and confront the absurdity of existence, drawing you into their unsettling, philosophical journeys.

If you found yourself fascinated by Grendel's morally complex nature—his violent acts, self-justification, and moments of introspection—American Psycho offers a similarly ambiguous, unsettling protagonist. Patrick Bateman’s thoughts and actions will challenge your sympathies and force you to question the boundaries of morality and identity.

If you loved the way Grendel reimagined Beowulf from the monster’s view, Circe will enchant you with its fresh, empathetic take on the infamous witch from Greek mythology. Miller’s lush prose and deep dive into Circe’s psyche provide a rich, mythological retelling that centers the outcast and the misunderstood.

If you were drawn to the intense self-examination and philosophical turmoil that Grendel endures, you’ll be riveted by Raskolnikov’s spiraling thoughts and moral agonies in Crime and Punishment. The novel delves deeply into the mind of a tormented outsider whose actions and justifications challenge the very nature of good and evil.

If you enjoyed the symbolic layers and mythic resonance of Grendel, The Master and Margarita will delight you with its blend of philosophical satire, fantastical events, and deep allegory. Bulgakov’s world, where the Devil visits Soviet Moscow, is rife with metaphor and invites endless interpretation—much like Gardner’s reimagined monster.
