The Grayson twins are moving to a new town. Again. Although it's a drag to be constantly mistaken for each other, in truth, during those first days at a new school, there's nothing better than having a twin brother there with you. But on day one of sixth grade, Ray stays home sick, and Jay is on his own. No big deal.

Grace and Ellie have been best friends since second grade. Ellie's always right in the center of everything - and Grace is usually happy to be Ellie's sidekick. But this time, it's Grace who suddenly has everyone's attention when she accidentally starts a new fad at school. It's a fad that has first her class, then her grade, and then the entire school collecting and trading and even fighting over...buttons? A fad that might also get her in major trouble and could even be the end of Grace and Ellie's friendship. Because Ellie's not used to being one-upped by anybody. 

What would happen if the noisiest, most talkative class of 5th graders in history dared each other not to talk for 48 hours? This is the premise Andrew Clements explores in one of his most compelling stories yet.

Mark Chelmsley IV has never felt truly at home anywhere. With only four months left in the fifth grade before he starts at an exclusive boarding school, Mark doesn't think it's even worth trying to settle in. What changes his mind is a Week in the Woods - the annual school camping trip. But even there, things go wrong. Mark covers for a friend and lands himself in Big Trouble: his nemesis, science teacher Mr. Maxwell, suspends him. Just as Mr. Maxwell is about take Mark home, Mark runs off into the woods, putting his survival skills - and Mr. Maxwell's - to the test.

Jordan Johnston is average. Not short, not tall. Not plump, not slim. Not blond, not brunette. Not gifted, not flunking out. Even her shoe size is average. She’s ordinary for her school, for her town, for even the whole wide world, it seems. But everyone else? They’re remarkable. She sees evidence everywhere - on TV, in movies and magazines, and even in the email blasts that fill her inbox. Tremendously talented. Stunningly beautiful. Wildly gifted. And some of them are practically her age! Jordan feels doomed to a life of wallowing in the vast, soggy middle. So she makes a goal: By the end of the year, she will discover her great talent.
