Katharine McGee is the New York Times bestselling author of the American Royals series and the Thousandth Floor trilogy. She studied English and French literature at Princeton University and has an MBA from Stanford. She’s been speculating about American royalty since her undergraduate days, when she wrote a thesis on “castle envy”—the idea that the American psyche is missing out on something because Americans don’t have a royal family of their own. She lives in her hometown of Houston, Texas, with her husband and sons.
