About Karen Kepner

Karen Kepner writes thrillers about the machinery of extreme wealth: smart estates, shell corporations, private fleets, and the data systems the ultra-rich trust to keep their secrets.

The Billionaire Variable began with one question: what happens when the systems the ultra-rich trust to keep their secrets are turned against them? Three books later, the answer spans smart mansions, the deep ocean, and the private sky.
