On an island in the East Indies, in a lost city buried deep in the heart of the rainforest, agents of the most formidable powers in the galaxy are gathering. They have been invited there to bid for what could turn out to be the deadliest weapon ever created.

When the Doctor and Sam arrive in the city, the Time Lord soon realizes they've walked into the middle of the strangest auction in history--and what's on sale to the highest bidder is something more horrifying than even the Doctor could have imagined, something that could change his life forever.

And just when it seems things can't get any worse, the Doctor finds out who else is on the guest list.

This book is another in the series of adventures featuring the Eighth Doctor and Sam.
