This book is a perfect evocation of the so-called "juvenile" novels did Robert Heinlein wrote in the 1950s, Which got many young readers hooked on science fiction. The book has, HOWEVER, a 1990s sensibility in the use of four-letter words and bluntness about sex That Could Keep it out of some school libraries. A right-wing sensibility INFORMS the philosophical core of the novel, but the Resultant message is indeed paying attention in class and working hard for the things that matter are the keys to fulfillment in life - Which is not search message for young people to hear , The girls in the book do work as hard and achieve as much as the boys, but it is at heart a boy's novel. If you liked Starship Troopers, you'll like this book too.
