Doctor Who: The Fifteenth Doctor: The Prison Paradox - Paperback

The Doctor continues his adventures through time and space alongside a team of allies from across the universe, fellow prisoners held captive in a maximum security space prison! Each has a story to tell and a role to play in uncovering the mysteries of their incarceration.

H-8 THE CYBORG: A ship of Theseus of pilfered cybernetics, H-8 doesn't remember what part of him is biological anymore, or what species he started out as. A hulking being obsessed with firepower, he's bristling with weapons- including a Dalek gun attached to his arm! Despite this, he's surprisingly affable. You'd like him. Conviction: Weapons theft.

FELIK THE SLITHEEN: Embarrassed by her family's history, Felik fled them to become the pirate scourge of two galaxies. Endlessly hunted by her own kind. Conviction: Piracy.

MEEZAN THE TENTACULON: An aquatic squid being made entirely out of twisting tentacles; Meezan is the last of her kind and very sad about it. After her underwater planet became a desert, she returned to try and flood it. Which was not taken well by the land-dwelling species that had come to settle there. Conviction: Attempted terraforming without a permit.
