After Worlds Collide (1934) is a sequel to the 1933 science fiction novel, When Worlds Collide. Both novels were co-written by Edwin Balmer and Philip Wylie. After Worlds Collide first appeared as a six-part monthly serial (November 1933 through April 1934) in Blue Book magazine. Much shorter and less florid than the original novel, this one tells the story of the survivors' progress on their new world, Bronson Beta, after the destruction of the Earth. Source: Wikipedia (en)
