The Styx have infested England, but they have plans that go far beyond the borders of England. Normal citizens from all over the world are attempting assassinations on the world's leaders. The only connection is that they've all been to England recently and all had organs removed and replaced with undetectable explosives. With the boarders closing, there is nowhere left to run and no one willing to help a nation that is seemingly a hub of terrorist activity. Will, Chester, and Elliot must figure out the purpose of this new Styx threat and why the Styx would want to isolate the entire British Isles from the outside world before the situation spirals out of control.

SPIRAL by Roderick Gordon and Brian Williams is the fifth book in the bestselling Tunnels series. This is the first book from the Tunnels series that I've read. I plan on finding all of the previous books so I can give them to my daughter. SPIRAL is packed with action, adventure, vivid descriptions that completely creep me out, and an amazing plot that went way beyond what I expected. SPIRAL is, quite simply, fun to read. Illustrations are tucked like hidden gems throughout the novel which I love. I'd spend a few minutes studying the picture, looking for clues to the story and appreciating the artwork.

SPIRAL is a pretty lengthy book at 440 pages, but it reads quickly and shouldn't be daunting. The prose is straightforward, descriptive, and fast. The story is easy to pick up even if you're new to the series like I was. Gordon and Williams carefully lay out all the crucial information in the beginning which does make the first few chapters feel a bit slow, but once the world is established the pace speeds up considerably. By the midpoint of the book I didn't want to stop reading. The world is intriguing to say the least and creepy enough to entice the readers that love those elements in their stories. There is a description of the Styx women that seriously made me feel queasy when I read it. That is wonderful writing and I applaud the authors for their talent and for knowing exactly what will engage their readers.

Roderick Gordon and Brian Williams delivers superb action, terrifying opponents, and a plot that will keep the reader turning the pages as fast as they can. SPIRAL is fantastic fun. I can't wait to see what is in store for the conclusion of this series.
