The Kollin brothers introduced their future world, and central character Justin Cord, in The Unincorporated Man. Justin created a revolution in that book, and is now exiled from Earth to the outer planets, where he is a heroic figure.

The corporate society, which is headquartered on Earth and rules Venus, Mars, and the Orbital colonies, wants to destroy Justin and reclaim hegemony over the rebellious outer planets. The first interplanetary civil war begins as the military fleet of Earth attacks. Filled with battles, betrayals, and triumphs, The Unincorporated War is a full-scale space opera that catapults the focus of the earlier novel up and out into the solar system. Justin remains both a logical and passionate fighter for the principles that motivate him, and the most dangerous man alive.
