Anachrophobia is a BBC Books original novel written by Jonathan Morris and based on the long-running British science fiction television series Doctor Who.

They learn that they have landed on a planet that is host to a war between two factions of humans: the Plutocratic empire and rebels known as Defaulters.

The Doctor brings the machine back to the present, and Ash and Norton are placed in quarantine and develop disorientation, anachrophobia, memory loss and physical trauma.

Lane goes to check Ash and Norton, but they attack her and in her rush to leave she tears her time proof suit.

Time then jumps back one minute, and lane contacts Bragg, giving Anji the chance to overpower him and return The Doctor and Fitz to the present.

Shaw releases the Doctor, Fitz and Anji and brings them to the lab as Mistletoe moves Bishop to the quarantine ward.

The Doctor warns him not to, as he fears that the infected are offered the chance to change their personal timelines, but if they do, they have their history erased and become empty vessels for the clock creatures to take over.

The Doctor and Anji seal themselves in the control room with Mistletoe, but it is too late for the clock creatures to rewind time.

Lane releases Ash, Bishop and Norton from the quarantine ward as Doctor, Anji and Mistletoe flee to the medical bay.

Anji cannot find the Doctor, until Fitz brings him back into the medical bay, having found him outside with no gas mask on.

Plutocratic soldiers mistakenly rescue Bishop, but as the Doctor pursues them, they go through a small patch of decelerated time with broken shielding and arrive at station One months later.

At the central audit bureau, they meet the Actuaries, robot accountants who have been running both sides of the war for profit.
