"Strange is the night where black stars rise. And strange moons circle through the skies. But stranger still is Lost Carcosa."

Kyle Hawkes has made a career chasing ghosts on camera, exploring haunted ruins and unraveling old legends. But when an unaired episode of his paranormal series leaks online, it triggers a chain reaction that unearths a scandal the Vatican buried decades ago.

From the alleys of London to the catacombs beneath Rome, Kyle and his partner Ella are hunted by a ruthless cabal obsessed with summoning the King in Yellow. Their only hope lies in tracking down Father Zacharias, a long-missing exorcist who once stood before the Masked God—and lost his mind.

As myth bleeds into reality and reason yields to terror, they must confront an ancient power whose secrets offer unspeakable power... and utter madness.

"Night fell, and the hours dragged on, but still we murmured to each other of the King and the Pallid Mask."
