title: Hidden Worlds: Amazing Tunnel Stories (Hidden! Series)
author:  Debora Pearson 
description: Anyone who has marveled at humans' ability to bore through mountains or build a network of subways and roads under cities and rivers, or even service areas under theme parks, will enjoy digging into some of the more amazing tunnels in history.... What makes the "amazing stories" even more enjoyable are the illustrator's clever, cartoon-like illustrations that show the tunnels and the activity in them and above ground.... Even if youngsters don't grab a shovel, they should be tempted to further study "the hole story," and have a new appreciation of the use of tunnels through the ages. (Linda Salisbury <i>ForeWord</i>)<br /><br />A good read-aloud choice with sufficient wow factor material to intrigue young listeners (even adults) and to initiate discussion or research. Many of the tunnels will be unknown to kids. Only a couple of them are still active: the mail system still used in Prague after 100 years, and the salt mine in Poland. However, kids could be motivated to compare tunnels they have heard of or might actually visit, e.g.. undersea car tunnels, the subway, railroad spiral tunnels, etc.... Recommended. (Gillian Richardson <i>Canadian Materials</i> 2002-09-06)
