There are three categories. The first are those who have their worlds turned upside down, the second are those who don't. The third category are those who save these worlds. Eva White fits into the first category. She just wants to be normal and go unseen. However, now with an offer to join a team of young dimension travelers she will find out about dimensions hidden from most of humanity's view. Yet, before she can go on missions of all different kinds of adventures with the team, Eva must first hone her skills in a school. But when that school's dimension goes on a killing spree, will Eva survive long enough to become part of the third category?
