A brief excursion to somewhere that is nowhere, which is Nastick's version, for her story's sake, of nonexistence. It begins with stuffy Mr. Radagast introducing Berkeley's theory of ""immaterialism"" to his bored seventh-grade class. But two boys get interested and, on the theory that if you can think something into existence you can think it out, soon the whole class is set to concentrating on making Mr. Radagast's textbook disappear. What the teacher doesn't realize, though, is that it's he, not the book, they are sending off. Soon, he dims and vanishes. But the two boys realize, each for his own reasons, that the teacher must be brought back; and so, each for his own reasons, they talk the class into sending them off too--to find Mr. Radagast and, as it happens, save him from his own sterile fantasy. Dreamer Conrad and spitball champion Damon's adventures in nowhere (which is pictured as a thick, gray fog) last only for the duration of a seventh-grade class period and take no more time to read. Nothing of import is brought back, but it's brisk and moderately diverting while it lasts.
