The Eye of the Tyger (novel)

Publisher's summary
Inhabiting a colony spaceship in the thirty second century are members of a religious cult that left Earth to find a world of their own. Their leader, Seraph, has downloaded his mind into the ship’s computers, but now he has gone silent, enticed and serenaded by a siren song coming from inside a black hole. Trapped in orbit around the void, Seraph’s followers are confused by his silence, and when the Doctor arrives with his friend Fyne seeking a cure to a raging Tyger-fever which has infected his companion, he finds a world on the brink of chaos.
