The Whoniverse For An Older Audience... WORLDWIDE SHIPPING
The Rani is a prisoner. Of the Tetraps. Those hideous rodent-like vampires over which she once ruled. No longer. The devious Urak,
   her erstwhile disciple, has turned the tables. The Rani is put on 
  trial. And condemned to death. A sentence to be commuted if she 
  exercises her unique scientific prowess to solve a problem threatening 
  to depopulate Tetrapyriabus.
  Famine. Shortage of food.
What food?
Blood.
Whose blood?
The answer is in the cells where a pair of kidnapped humans and a pair of aliens
   are incarcerated. Destined to become the subjects of a brutal 
  experiment. The Rani forges an unholy alliance with the four 
  "guinea-pigs" in a perilous attempt to escape the nightmare of the 
  planet...
