Nash Falls is a pulse-pounding thriller by #1 New York Times bestselling author David Baldacci, the first book in the new Walter Nash series. Published by Grand Central Publishing (Hachette Book Group) on November 11, 2025, this 448-page hardcover follows Walter Nash, a successful executive at Sybaritic Investments who enjoys a comfortable family life with his wife and daughter.

Following his estranged Vietnam-veteran father's funeral, Nash is unexpectedly recruited by the FBI to become an undercover operative tasked with exposing a massive money laundering operation within his own company. The target is Victoria Steers, an international criminal mastermind that the FBI has been trying to bring down for years. When Steers discovers Nash's involvement with authorities, she turns the tables on him in a way he never could have contemplated, forcing Nash to take the ultimate step both to survive and to seek revenge. He must become the exact opposite of who he has always been.

Publishers Weekly notes that Walter Nash is among the most memorable of Baldacci's heroes, while Library Journal calls it a worthwhile investment. This gripping thriller sets up a duology with the sequel Hope Rises scheduled for April 2026.
