Sam and the teens who are immune to the voidborn are back to answer a distress call in Scotland. Upon their arrival something is wrong. A new threat appears. There is an army of immune people who plan on unleashing horrible creatures into London. Can Sam and his friends stop this new found enemy, or will London perish under his hand?

I really enjoyed reading this book. It is a perfect mixture of science-fiction and real life.  Mature content is PG because of the affectionate talking and well described alien deaths. Violence is PG because there is a war that makes up the gist of the book.
