Help! I need book recommendations?

If you liked Of Mice and Men, then you should read Steinbeck's masterpieces, The Gs of Wrath or East of Eden. You might also enjoy William Faulkner (As I Lay Dying, The Sound and The Fury, Absalom, Absalom). You might also want to try a little more modern day writers like Cormac McCarthy (The Road, No Country For Old Men, The Orchard Keeper) and Toni Morrison (Beloved, Paradise, Song Of Solomon).
