Formic Wars: Burning Earth #4
The casualties are piling up, but they're nothing compared to what happens next: the Formic ship arrives at Earth, and it quickly becomes apparent that the Formics have their own plans for our world -- plans, incidentally, that do not include the human race. Man's desperate battle for survival begins...with a little help from a soldier named Mazer Rackham! From bestselling author and science-fiction master Orson Scott Card, the all-new prequel to Ender's Game continues now.
