Publisher's summary
The Doctor is recruited by Leela for a vital mission on behalf of the Time Lords.

Together, they must track down and destroy two god-like beings whose extraordinary powers now threaten all of space and time.

Their names are Abby and Zara...

1. The Garden of Storms

In pursuit of Abby and Zara, Leela pilots the TARDIS to the eye of a violent storm in time. Yet she and the Doctor find themselves in an idyllic garden city, the people contented and happy. They soon discover that this bliss comes at a terrible cost, and that Abby and Zara are determined to put things right… so how can Leela and the Doctor stop them?

2. The Moonrakers

Life is hard for the early pioneers building the first settlements on the Moon. The laws of Earth don’t apply here, and there are tussles over limited resources vital to survival. Arriving on the Moon, the Doctor and Zara discover that an aggressive alien species lies in wait. Yet there’s something very strange about these particular Sontarans: they refuse to fight.

3. The People Made of Smoke

Abby and Zara strive to use their powers for good but it’s clear they are damaging reality - and allowing monstrous creatures to bleed through from beyond. The Doctor knows he can only save the universe by destroying his friends. But just how much might he be willing to sacrifice if there’s a chance to save them?
