I do not recommend this book for children at all. It has no story line, and although it does provide facts about volcanoes, it does so in a very confusing and incomprehensible way for children.
The method that Peters' used to convey said information (about volcanoes) was to give five different perspectives about the volcano to the reader. These including the volcano itself, a nearby fern plant, a cricket, the "small black road" going up to the volcano, and the sun/moon. The cricket speaks in "text talk" for example: "Hey, bro, where R U? I know it's early a.m. :-<." Although the reality of modern-day society is that children are, in fact, exposed to such talk at a young age, authors should not encourage this. Furthermore, the conversations between the sun and the moon are in no way understandable... The wording is poetic jargon to kids.
Children's Books are supposed to be fun, easy-to-read, easy-to-understand stories that provide useful and easily-understood information. "Volcano Wakes Up" fits none of these criteria.
My vote: don't buy this book.
