The Swifts: A Garden of Vipers (Hardcover, 2026)

"An ambitious and intricately plotted caper that will have readers riveted until its final, and supremely satisfying, sleight of hand." --The Wall Street Journal

After catching a murderer at the family reunion and solving a century-old art caper, the Swift children have built a reputation as expert sleuths. But when cousin Atrocious needs help to solve a murder in New York City, Shenanigan is wary until she finds out the victim is connected to their old friend Daisy DeMille and her family's flower empire. Trapped by a snowstorm in the DeMille's high-rise greenhouse headquarters, Shenanigan will have to weed out the poisoner hiding among the plants.

For their new adventure, Shenanigan and the beloved Swifts are joined by another eccentric, and fabulously fatal, family--the American DeMilles, including flamboyant heir-apparent Dandelion, ambitious brother Basil, and tenacious siblings Moss and Delphinium. The Swifts are back with their trademark witty wordplay, murder mysteries, and, of course, shenanigans.
