As usual, I paid nothing for this book but instead received a copy for review from NetGalley. Despite that kind consideration I give my candid thoughts below.
"Secrets Underground" is a very accessible yet detailed story of six different locations on the continent that have something buried underground. In some cases it's actual open passages or rooms and in others it's just remnants of some bygone era. The average section is about 15 pages long and features 12 photographs from half a page in size to thumbnails so this is about 70% text and 30% color photos. It's primarily textual and probably appropriate for 10-12 year-olds.
On the positive side, the author has chosen some very intriguing locales and it makes me want to travel more just reading a bit about them. Also, as I said the text is detailed enough to keep a young reader's interest but very careful to define words that kids probably wouldn't know.
To the negative, many of the photos are rather small and some pages are decorated with abominable clip art of digging implements. The graphical layout seems rather unprofessional and at times distracting.
In summary, the book lives up to its name and offers widely varied information on those mysterious bits lurking underground. It could use a bit more polish but it's sufficient to keep kids interest.
Elizabeth MacLeod is a name I delight to see on Canadian/North American history books for children. I'm quite fascinated with this topic and enjoyed the book immensely. Covering the whole continent famous underground places are discussed in Mexico,US,and Canada. Each place starts with a fictional teaser paragraph or so and then turns into straight nonfiction. Lots of pictures and told in an engaging voice. This is an entirely readable history/geography themed book with a touch of science. I ended up googling a couple of the places mentioned and added them to my hope to visit someday list.
