Example Input: Enjoyable by young and old alike! . The earth is surrounded by a sinister presence - a dark, foul fog that is the tool of an ultimate evil - whose ambition is to enslave the planet with the complete removal of free will. Three magical beings, Mrs Whatsit, Mrs Who and Mrs Which - witches, angels, demigods perhaps - appear to Margaret and Charles Wallace Murry and their friend, Calvin O'Keefe, to persuade them that it is their destiny to battle this evil on its own turf and to rescue Margaret and Charles Wallace's father. Dr Murry has been missing for some months and the kids learn that he has been captured by the evil while he was "tessering", traveling time and space in the course of his scientific research.    While the writing is straightforward, well crafted and obviously aimed at a younger audience, "A Wrinkle in Time" is nonetheless a fast paced enjoyable tale of good vs evil that combines elements of science fiction, fantasy and magic even adult readers will flip through relentlessly. But there are lots of life lessons, issues and moral themes sprinkled throughout - low hanging fruit just waiting for the eager child, the observant questioning teen, the confused parent or thinking adult to pick and chew on, as it were - the coming of age realization that parents are not infallible; the cruelty of malicious gossip; God and evil; the awkwardness of romantic adolescent relationships; the potential destructiveness of pride or vanity; the marginalizing of people who are different; the enormous difficulties of selflessness; the understanding that all life's questions will not be answered; and more.    While some readers criticize "A Wrinkle in Time" as being overtly moralist, I felt somewhat differently. It was clear to me that religion and, in particular, Christian symbolism was present but I felt that L'Engle let it sit quietly just beneath the surface and the story never became even remotely preachy.    It is little wonder that "A Wrinkle in Time" has been elevated to the status of children's classic and continues to be enjoyed by adults and children alike more than 40 years after it was first published for a grateful reading world.

Example Input: Championship Ball by Coach Clair Bee . The book I read was Championship Ball, by Clair Bee. Championship Ball is about a high school basketball player named Chip. Chip is an extremely good athlete and is a starting basketball player for his high school. Everything was going great until something happened that would change Chips life forever. During a basketball game Chip got tripped up and hit the ground hard. As Chip was writhing in pain, the team trainer came out to assist him. As it turned out Chip had fractured his ankle in several places. It was pretty bad which would mean that he would have to watch the games from the team bench for the rest of the year most likely. As his team goes on without him, they are doing quite well. They are making a championship run, and they are doing quite well, and they eventually get there. Before the big championship game, Chip was begging his coach to let him play. Chip's coach is not sure if Chip is  ready to play just yet, but Chip is by far the best athlete on the team. Will Chip get to play in the big game, or will he have to spend yet another game spectating from the bench.  I really enjoyed the book because it is very suspenseful, and it is hard to put down. It is suspenseful because throughout the book the author does not tell you Chips condition in its entirety, and whether or not he will get to play in the up coming games. There was on thing that I did not like about the book and that is the repetitiveness. It seemed like every time a big game was about to unfold, the same thing happened on the court. Also every time Chip asked his coach to play, he always said no, so you kind of almost expect it.   My strongest reason for recommending this book is that it is very well put together. Also if you are into sports or you like suspense and action, then you will probably love this book because it has all of these aspects.
