They’re called The Passenger and Stella Maris:
Cormac McCarthy is publishing two linked novels this fall: The Passenger on October 25 and Stella Maris on November 22. (Or you can wait until December 6 to get your boxed set.)
I’ve read every McCarthy novel, and I’ve been waiting years for something new to read from him. He’s the type of writer I wish I was, and I always look to him for inspiration and guidance. I. Am. Excited.
Also, apparently, he submitted drafts for these two novels eight years ago. Unbelievable.
