Tony notices that his brother, Carl, has stopped eating, listening to music, seeing his friends...in fact, stopped doing anything that de used to enjoy. Has Carl been taken over by an alien? Tony knows that the best way to find out the truth is to tempt Carl with his favourite food - because aliens don't eat bacon sandwiches...do they? The themes and settings in this wonderful collection of eleven stories vary from the ghostly experience of The Airman's Sixpence, the drama of A Gap in the Dark, the future-shock of The Mars Ark and the fantastical Aliens Donlt Eat Bacon Sandwiches.
