The Hand of Erebus - Chronicles of the Collapse, #4

The Hand of Erebus (Chronicles of the Collapse, Book 4)The world was unravelling. Nathan knew it now, thought there was little that he could do about it. Though he possessed technology that might be helpful someday, his understanding of it was limited and tinkering with it could have catastrophic consequences. With more immediate and pressing matters to attend to, he continues the daily struggle to survive and make something of the fledgling community that he and his friends have set up.
There are others, however, that have taken note of the recent events in Albertville. Others that wish to possess the technology and knowledge that Nathan has gained. Others that will resort to any means to secure their goals. Nathan and his friends are soon plunged once more into the midst of violence and this time one thing is beyond doubt. None of them will come out of it unscathed.
