Tom Clancy Executive Power is the 26th installment in the #1 New York Times bestselling Jack Ryan series, written by Brian Andrews and Jeffrey Wilson and published by G.P. Putnam's Sons (Penguin Random House) on November 25, 2025.

When a covert Defense Intelligence Agency mission in Luanda, Angola goes catastrophically wrong, Kyle Ryan—youngest son of President Jack Ryan—becomes the sole survivor, forced to run for his life after his two colleagues are killed. As the ruthless Angolan warlord Victor Baptista launches a violent coup against the country's democratically elected government, Kyle is captured and faces execution, unbeknownst to his father. Navy Lieutenant Commander Katie Ryan and her unit are dispatched to rescue stranded Americans, while President Ryan marshals the full weight of U.S. executive power from the White House to bring his children home.

Andrews and Wilson place the youngest Ryan siblings—Katie and Kyle—at the center of a tightly plotted geopolitical thriller that blends family loyalty with international intrigue. Kirkus Reviews praised the novel, noting "the youngest Ryans will please fans of the genre."

This hardcover edition runs 464 pages and is also available in large print, ebook, and audiobook formats narrated by Scott Brick (13 hours, 20 minutes). ISBN: 9780593718063.
