The Darksmith Legacy: Bk. 4: The Depths of Despair
Justin Richards
The Doctor arrives in an underwater base on the planet Flydon Maxima – known locally as Despair because hope is lost for all life there. The Doctor is helped by a little girl called Gisella. Why did Varlos risk coming here? What has caused the ice to crumble so rapidly now? Who is Gisella and will she and the Doctor manage to escape in the TARDIS?
