Aya Katz is a libertarian author, linguist, and primatologist. Her writing is geared toward an exploration of freedom and how we should go about getting and preserving it. The recurring themes in her books deal with justice and honor. Katz is internally motivated, and tends to take the side of people who act on internal rather than external compulsions.
Aya Katz's first novel The Few Who Count was published in 1983. This novel is written at a YA level and explores the concept of commercial chastity.This is the idea of not selling out for the profit motive alone, but pursuing business interests based on an internal driving force. In this novel, Hannibal involves his teenage daughter Caldwell in making business decisions for Carthage Corporation, which is a theme not often explored in this genre. Another key point discussed in this novel is about how the limited liability for corporations actually infringes upon free enterprise, and the rights of individuals should never be suppressed over the rights of the collective.
Vacuum County was Katz's first adult genre novel published in 1993. This tale begins with the young woman Verity being unlawfully accused of DWI in a small Texas town, where she is forced to stay against her will. The story branches out to cover a cast of characters and addresses the concept of how all people can work together to promote personal liberty, even if it is not a motivating factor for most people. Vacuum County was written prior to the Mount Carmel massacre, but explores the non-aggression principle. Sometimes the government must intercede in a time of crisis, but the novel discusses how this should only occur when individual liberties are at risk.
