David Eckersley is a survivalist who is busy equipping his underground bunker with water and crappy food and lots of guns. He's part of a compound (ok, it's really more of a trailer park) that calls itself Safe Haven. Victoria, his daughter, seems like a normal teenage girl (in other words, she's not all that interested in trailer park survivalists). The Safe Haven residents are quite worried that the gov'mint might take away their guns. Turns out the survivalists would have survived if they hadn't had any guns. Ironic, that.
One of the survivalist's kids is named Lucas. He's the pack leader who all the other kids blindly follow. He has a plan. I wasn't convinced that that other kids would buy into Lucas' plan (and the crisis for which he sees a need to plan) since any rational person would quickly conclude that Lucas is a psychopath who needs a psychiatric commitment. Victoria spots the flaw in Lucas' thinking instantly. If she can do it, why can't the other kids? None of Lucas' friends ever noticed before they arrived at the camp that Lucas is a nut job? But that's the story and, implausible though it might be, it held my interest.
Sheltered teaches a cool lesson: If you teach your children not to trust, they won't trust you; if you teach them extreme beliefs, they will take extreme action; if you teach them that the end is coming, they might be the end of you. Sheltered also has something to say about survivalist culture. The story is marred by its failure to provide a more convincing explanation of the motivation for the kids to act as they do -- and that's a serious flaw, given that their actions are central to the story -- but I enjoyed reading it anyway. I liked it, so it gets four stars, but a weak four stars.
