The Hive (The Second Formic War, Bk. 2)

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?
