Mathematics, like language, is a universal experience. Every society counts and is empowered by its ability to count and to measure. The mathematical processes developed within various cultures differ widely, and Count Us In explores these cultural links, drawing examples from the author's personal experiences. The process of counting, like the process of communicating with words, is common to all societies worldwide but, just as there is a rich variety of languages, so too is there a rich variety in methods of counting and of recording numbers - methods that have developed over centuries to meet the needs of various groups of people. The narrative of this book takes the form of a collection of short stories based on the author's personal experience, linked together by a number of sub-themes. As a popular book on mathematics and on the personalities who created that mathematics, there are no prerequisites beyond the reader's rudimentary and possibly hazy recollection of primary-school mathematics and a curiosity to know more.

Laid claim to by disputing factions of humans and Chelonians, the planet Barclow has become the catalyst for an unusual war. In two hundred years of hostilities not a shot has been fired, and the opposing combatants are the best of friends. But tensions are growing. Someone, somewhere is trying to make this well-mannered war very angry indeed.

Equipped with space suits, golf clubs and a flag, the Doctor and Rose are planning to live it up, Apollo mission-style, on the Moon. But the TARDIS has other plans, landing them instead in a village on the south coast of England; a picture-postcard sort of place where nothing much happens. Until now... An archaeological dig has turned up a Roman mosaic, circa AD 70, depicting mythical scenes, grapes and a Dalek. A few days later a young woman, rushing for work, is knocked over and killed by a bus, then comes back to life. It's not long before all hell breaks loose, and the Doctor and Rose must use all their courage and cunning against an alien enemy and a not-quite-alien accomplice who are intent on destroying humanity. Featuring the Doctor and Rose as played by David Tennant and Billie Piper in the hit Doctor Who series from BBC Television.
