Probably one of the best books I have ever read. Its sense of mystery made me want to keep reading forever. Anyways, it's about a group of children who all pass a series of tests set up by Mr.Benedict, who is looking for a group of children to help him defeat Mr. Curtain, the leader of the Learning Institute for the Very Enlightened, and Mr. Benedict's twin brother. To do this, the children- Kate, an energetic girl, Reynie, an excellent leader, Sticky, a walking dictionary, encyclopedia, thesaurus and calculator, and Constance, a stubborn 3-year old toddler whose gifts prove to be the most important, have to go to LIVE themselves to find out more about Mr. Curtain' plots. If I said any more, I would ruin the story, so- i guess- that's all!
