Oathbringer Part One: The Stormlight Archive Book Three, Paperback Book, by Brandon Sanderson

Defiant, the fourth and final volume of the series that started with Skyward in 2018, comes out in November 2023, capping an already book-filled year that will see the releases of all four Secret Projects: Tress of the Emerald Sea, The Frugal Wizard's Handbook for Surviving Medieval England, Yuma and the Nightmare Painter, and Secret Project Four (with its official title reveal coming October 2023). These four books were all initially offered to backers of the #1 Kick-starter campaign of all time.
