In this one-shot prequel to the award-winning novel Ender's Game, Mazer Rackham, the only man ever to defeat the Formics, takes on a new enemy…the International Fleet itself. Burdened with careerists and bureaucrats, the I.F. is doomed to fail in the coming war, and only Rackham, with the help a young Hyrum Graff, can rid the I.F. of its old guard and pave the way for Earth's next great commander. Adapted from Orson Scott Card's short story, MAZER IN PRISON is a look into the beginnings of the system into which Ender Wiggin found himself thrust.
