Magic Tree House
Junie B. Jones
Four of the Outcasts don't really participate in class, and all five could care less about a group activity, so the fact that all of them actually go on the fieldtrip is something of a miracle.
And when reality splits, and they end up in another dimension, you can imagine how badly they'll all wish they'd stayed home. Five outcasts fall out of reality. How many will make it back to the world as they know it?
