The blood cell

"An asteroid in the furthest reaches of space -- the most secure prison for the most dangerous of criminals. The Governor is responsible for the worst fraudsters and the cruellest murderers. So he's certainly not impressed by the arrival of the man they're calling the most dangerous criminal in the quadrant. Or, as he prefers to be known, the Doctor."--Amazon.com.

The Doctor is the newest inmate at the most secure prison in the universe and immediately starts trying to escape; the Governor, the man responsible for the entire prison, sets out to find out why.
