When Jon Morris last contributed to DW fiction, it was the wonderful Festival of Death, which used a great mix of humor, action, horror and a convoluted plot to amazing effect. It's been hailed upon its release as one of the best PDAs under the BBC banner, and one of the best DW books overall.

With all that praise, it wouldn't be surprising if Anachrophobia suffered from the sophomore jinx.

Thankfully, it doesn't.

Jon Morris gives us something different. Anachrophobia is creepy, malevolent and downright frightening in parts. If you're expecting the laughs that came from Festival, you might be disappointed. Morris shows us that he can use some of the creepier moments from that book and expand upon them for a full novel.

The basic premise of Anachrophobia is that the Doctor, Fitz and Anji land on an unnamed planet where two armies are fighting a war where time itself is the chief weapon. Like Festival, Morris picks a concept so obvious that it makes you wonder why no other writer tried to use it earlier. From there, the TARDIS crew arrive at isolation station 40, where experiments into time travel are being conducted as the possible next weapon.

Characterisation is very strong. The Doctor, Fitz and Anji are all done very well. Like Hope previously, Anachrophobia takes into account the result of the events that occurred in The Adventuress of Henrietta Street, and how they affect the Doctor. I loved the general attitude of the Plutocrats - the side who works at Station 40 - which is Ayn Rand's ideal of capitalism taken to an illogical extreme. This is idealised in Mr Mistletoe, an auditor who arrives on the station partway through the novel. Mistletoe is a complete weasel, and so much more.

Morris does play around with cause and effect. However, not in the basic structure of the novel, but we see in several key scenes that help drive the main plot. The story itself moves and twists along, with Justin Richards corkers coming left and right in the last third of the book.

I will say no more about this book, as to spoil it for others would be wrong and should be punished by forced repeated viewing of Buffy the Vampire Slayer (similar to poor Alex in A Clockwork Orange) till the brain turns into tofu.

Just buy it, read it and enjoy. It's that brilliant.
