Long before interplanetary exploration and a certain rock group, Robert A. Heinlein wrote this science fiction classic (Random, 1977). Mischievous teen twins Castor and Pollux Stone set the story in motion with a plan to make their fortune as space traders. Soon they are waving goodbye to their home on the Earth's moon and they're headed for Mars with their parents, sister, younger brother, and grandmother. The Stones are an intelligent, strong-willed clan, so there are squabbles during their months of weightless flight...

Sadler, one of England's top grandmasters, has a knack for demystifying some of the more abstruse aspects of the game and presenting them in a clear and easily understood manner.
He surveys many chess themes in a style that will neither bore nor frighten "younger" (and/or newcomer) players.
This is a highly recommended, first rate "how to" book that chess beginners will appreciate.
