As one of Earth’s Galactic Enforcers, Lawn Bascomb is assigned to Area R6Y6 for the duration of one year. Her only companion in this desolate section of space is Deep, her sentient Vogt ship.

The Vogt line is an experimental breed of unique vessels, each with its own artificially enhanced intelligence, created specifically for use at the deep space guard posts. Able to project himself in holographic form, Deep is not only Lawn’s sole fellow crew member, but he is also her confidant and friend. It isn't long before he becomes her lover.

But their tenuous arrangement is suddenly and fatally shattered when their post is threatened by an unknown and perhaps alien force. Lawn and Deep soon face the realization that, in order to save Earth, one—or both of them—must die.
