The sequel to Crypt of the Moon Spider, Cathedral of the Drowned is an oozing, squirming, scuttling tale of altered bodies and minds.

There are two halves of Charlie Duchamp’s brain. One is in a jar stranded on Jupiter's jungle moon, Io, who just wants to go home to the woman he loves. The other half is still locked in his body, hanging from a wall in Barrowfield Home on Earth's own moon, host to the eggs of the Moon Spider and filled with a murderous rage.

On Io, deep in the flooded remains of a crashed Cathedral ship, lives a giant centipede called the Bishop, who has taken control of the drowned astronaut-clergy inside. Both Charlies converge here, stalking each other in the haunted ruins, while more Moon Spiders prepare to be born.
