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. One is a brain in a jar, stranded on Jupiter's jungle moon, Io, who just wants to go home. The other is hanging on the wall of 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 astronauts inside. Both Charlies converge here, stalking each other in the haunted ruins, while a new Moon Spider prepares to hatch.
