Billy Pilgrim has read Kilgore Trout and opened a successful optometry business. Billy Pilgrim has built a loving family and witnessed the firebombing of Dresden. Billy Pilgrim has traveled to the planet Tralfamadore and met Kurt Vonnegut. Billy Pilgrim has come unstuck in time. Slaughterhouse-Five is at once a farcical look at the horror and tragedy of war where children are placed on the frontlines and die (so it goes), and a moving examination of what it means to be a fallible human.
