The Illearth War (The Chronicles of Thomas Covenant the Unbeliever, #2)

by Stephen R. Donaldson

Hile Troy was sure of one thing; despite whatever Covenant said, the Land was no dream. He perceived this with an acuteness which made his heart ache.

Hile Troy gets his own POV. There are 2 options. [1] Troy and Covenant are participating in each other's dreams with all the same scenery and generated dream figments, or [2] The Land is real and they have been transported to this reality. By Occam's Razor, the Land is real.
