Card and Johnston continue the fast-paced hard science fiction history of the Formic Wars--the alien invasions of Earth's Solar System that ultimately led to Ender Wiggin's total victory in Ender's Game.
A coalition of Earth's nations barely fought off the Formics' first scout ship. Now it's clear that there's a mother-ship out on edge of the system, and the aliens are prepared to take Earth by force. Can Earth's warring nations and corporations put aside their differences and mount an effective defense?
Ender's Game is one of the most popular and bestselling science fiction novels of all time. The Formic War series (The First Formic War and The Second Formic War) are the prequels to Ender's story.
