The date isn't confirmed in any way, but the HarperVoyager listing for The Desert Prince shows what looks like a May 13, 2021 release date for the paperback: https://www.harperreach.com/products/the-desert-prince-peter-v-brett-9780008309787/
There probably is no historical analog, but maybe Krav Maga?
PVB?
Not sure how I missed this for so many months...
"The new series, the first of which is titled The Desert Prince, will take place 15 years after the ending of The Core telling the tales of two young protagonists, Olive Paper and Darin Bales, and featuring Demon Cycle characters and settings."

Very cool.
Where is this from?
The Core, plus The Painted Man, The Desert Spear, The Daylight War, and The Skull Throne.
