"Dear Doctor", wrote Chris, "I give up".

Swordplay, samurai, demons, magic, aliens, adventure, excitement... Who needs them?

The Doctor and Chris travel to 16th-century Japan, a country gripped by civil war as feudal lords vie for control. Anything could tip the balance of power. So when a god falls out of the sky, everyone wants it.

As villagers are healed and crops grow far too fast, the Doctor and Chris try to find the secret of the miracles — before the two rival armies can start a war over who owns the god.

Chris soon finds himself alone — except for an alien slaver, a time-travelling Victorian inventor, a gang of demons, an old friend with suspicious motives, a village full of innocent bystanders, and several thousand samurai.

Without the Doctor, someone has to take up the challenge of adventure and stop the god from falling into the wrong hands. Someone has to be a hero — but Chris isn't sure he wants to be a hero any more.
