If you like scify this book will tick all the boxes you have. Imagine lord of the flies combined with something other...something not quite right. The main character Bensen, a foster child, is dropped in the middle of a upscale academy where kids roam free under the guidance of unknown benefactors. This is the basis for many dreams people have had everyone has had that one moment where as a child they thought to runaway and live without your parents/guardians rules. This books takes it into perspective and shows what happens if kids rule themselves with some help from people who want to test, experiment, observe what would happen when this occurs. Imeagerly anticipated the ending and will read the next book feedback to see how the book comtimues. 
 Wells drops you into a world of chaos where teenagers are made to act like adults when in truth they dont know what to do when one wrong move could get you hard manual labour and no food or worse. Its lord of the flies only more modern and with a new twist to it. What makes this so real is the children taken are children who will not be missed, foster children believed to be going to a big shot school but with nobody to think of them or worry if they don't come back in the holidays. The author capitalised on the possibility and sets up a believable account of what could be with the mystery of why they have been taken. 
 The teenagers are confused, scared, frightened and yet while some submit under the rule of the ice man others step up and try to escape wanting a better life where they can be free but none know just how far the conspiracy runs nor why the 'experiment' goes on.
