The Doctor’s TARDIS has brought him to celebrate Christmas in many strange times and places, but few have been more alien than Yesod – a brown dwarf world orbiting the double sun of Kether-Tiphereth, where limbless children dance in the gas-currents and many-armed elders tell stories of a vanished past.This one isn't a villanelle or anything clever, it's just the label which tells you what's inside the tin. If it makes the contents sound intriguing, then for heaven's sake buy the book.
Yet the Yesodites have their own midwinter rituals, even though the Long Midwinter comes only once in five generations. The Doctor and his friends will soon discover that millions of years in the future, trees and gifts and midwinter fires have taken on a very different significance...
This story features the eighth Doctor, Gemma and Samson.
