Who or what is the First Wolf? That is the question that haunts Mystere and Kalen Vale as they languish in a mystical prison deep beneath an ancient village. Forced to rely on one another, the two erstwhile adversaries must face deadly traps, haunted echoes of the village’s past, and the looming awakening of something far older and more dangerous than they expected, as they try to escape alive while learning the truth they seek. Meanwhile, at Arcane Acre, as Keres reels from a devastating psychic blast from the Tome of Blood and Shadow, she reaches out to the one man who understands the book and the darkness within it—Henry Lovecraft!
