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.
