Publisher's summary
8.1 The Sinestran Kill by Andrew Smith

When the Doctor decides to trace an anomalous energy signature on twentieth century Earth, he stumbles into an assassination attempt. Gangland thugs are trying to murder a seemingly innocent shopkeeper, and it’s only the intervention of the Doctor and Ann Kelso – a WPC who happens to be on the scene – that prevents a tragedy. But why do the gangsters want the shopkeeper dead? And what does this have to do with alien technology? The first stages of a grand conspiracy are about to be revealed. And finding the answers will take Ann Kelso on a journey like no other. 8.2 Planet of the Drashigs by Phil Mulryne

When the TARDIS lands on an alien planet, the Doctor's intentions to show Ann Kelso an advanced future society are thrown into disarray. Because they have arrived on DrashigWorld - a park where every known species of the terrifying predators has been gathered together to entertain and thrill the public. The familiar wetland Drashigs, the albino burrowing Drashigs of the desert, and deadliest of all, the tiny Emerald Drashigs of the rain forests. And it’s not the best day to have arrived. The park has been shut down due to a visitor fatality. A Galactic Attractions inspector is on site meaning everyone is extremely tense and under pressure. It's exactly the right circumstances in which someone might make a mistake. And on Drashigworld, mistakes are deadly. 8.3 The Enchantress of Numbers by Simon Barnard and Paul Morris

The TARDIS lands in the grounds of Newstead Abbey, Nottinghamshire, in 1850. Mistaken for a medic and his maid, the Doctor and Ann are brought to meet Ada Lovelace - the mother of computing and daughter of Lord Byron - who has recently fallen ill. But the travellers are not here by chance. Something odd is happening on Earth, and they’ve determined that this place is the centre of it. Strange figures are walking the land. Strange figures wearing bird-like masks. What do they want with Ada? And how will it change the future of humanity? 8.4 The False Guardian by Guy Adams

Ann Kelso doesn’t like mysteries. Keen to investigate the trail of the Sinestrans, she sets the TARDIS on a new course... but flies into danger. Arriving on a desolate world that the Doctor finds somehow familiar, the TARDIS crew discover that something is wrong with time. The inhabitants of an unusual complex are experimenting at the command of their enigmatic director... somebody who has quite a strong grudge against the Doctor. Facing an old foe who was presumed dead, the travellers are soon trapped in a diabolical scheme. But is it just the tip of the iceberg?
