Seeing I

Seeing I is an original novel written by Jonathan Blum and Kate Orman and based on the long-running British science fiction television series Doctor Who. It features the Eighth Doctor and Sam.

As with all Doctor Who spin-off media, its relationship to the televised serials is open to interpretation.

The novel is partly set in a private prison called the Oliver Bainbridge Functional Stabilisation Centre, in which corporate spies and those who know too much are held. Orman's later novel Blue Box featured a high security mental institution called Bainbrige Hospital with a similar remit.
The Time Lord Savar from The Invasion of Time is briefly mentioned; the loss of his eyes here ties into his appearance in The Infinity Doctors.
