I'm enjoying it. It is definitely aimed at the young adult audience because the main characters are teenagers (although clearly not the actors). It is split into scenes between those trying to survive on Earth, and those trying to survive on the space station. In both cases there is a question of leadership, politics, and ethics, about decisions that are made that affect everyone. I prefer the scenes on the space station, which involves more debate through intellectual discussion, while on the planet it is more physical, and theres more action.
