This was another great write by Greig Beck. The first book by this author was Beneath the Dark Ice which was a damn good read. This one had the same main character so although it was not directly related to the book, it was a continuation of one soldier's adventures.
In comparison to the first, the story in this book concentrated on a scientific anomaly of a black hole as opposed to ancient, lost history which the first book was all about. I believe I liked the first one better, just because of the plot, but the action and general writing were just as good in this book. Read the first; if you like it you should like this one as well.
