It's set in a part of BATTLWORLD (I don't know why I always all-caps that word) that has been all but completely destroyed by "the bugs" -- giant bug-like alien life forms that eat people. It's the story of Anwen and her family in the desolate post-apocalyptic landscape, trying to survive and evade these bugs. Her mom had left to join the Nova Corps in efforts to stop the bugs but it's been years and they haven't heard from her, or them, since.
