Horn Book Review
This fourth book follows aptly named Will Burrows (Tunnels, Deeper, Freefall) and his friends as they traipse back to the world at Earth's core and to Topsoil. Though the story line attempts to follow too many characters--including clever heroes and even more interesting villains--the book's fast-paced action will sustain fans. Readers are again left hanging off a cliff at the end. (c) Copyright 2011. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
Booklist Review
In this latest entry in the Tunnels series, the struggle continues between the few Topsoilers in the know Will, Elliott, Chester, Drake, and their crew and the Nazi-descended Styx, led by twin sisters Rebecca One and Two, who are determined to reclaim vials containing the deadly Dominion virus and obliterate the (non-Styx) human race. Gordon and Williams move characters and plotlines around like two generals directing a simulated battle. Chapters alternate between various individuals and groups, and knowing the background is essential to keeping up with the jumps. This installment is a bit long-winded, but its authors have created quite a world.--Welch, Cindy Copyright 2010 Booklist
