Baseball is Roger McGillicutty's whole life. That is until one Saturday morning when he mysteriously changed from a normal eleven-year-old boy to a five-foot-tall praying mantis. Roger has school on Monday, the carnival comes to town next week, and his baseball team is poised to play their biggest rival in one week. Being a giant bug will seriously cramp Roger's style! But baseball may be the lease of Roger's worries. Some people are frightened and others would like nothing more than to squash him into the ground like the bug he is. When a reporter form the city coes snooping around rumors of a man-sized baseball-playing praying mantis, Roger must choose between hiding his true self or being the hero he's alwas wanted to be.
