The Intruder

"A mineral has been discovered deep beneath the surface of the moon that produces bumper crops, grown in massive domes at the lunar base. The sole occupant of Moon Base is Luca, whose lonely job it is to supervise the computerised supply chain. A few days before the end of his posting, and his return to Earth, communications with Earth fail and Lucás ordered, monotonous world is further disrupted by an unknown intruder. Who or what is it? Where did it come from? What does it want? Is it friend or foe? Luca must find the answers to these questions on his own, as Earth is a long way away"--Back cover. Includes discussion questions.
