This comes from a series of books that I can easily get my kids to read. The text isn't particularly challenging, but it does cover something that my kids ask about a lot. The pictures are interesting enough and I know that I'm not handing my children anything that I will regret later on when I lend this out (which is a problem that I run into a lot with this sort of book). This, like other series from Creative Education, does a good job of being tactful, yet interesting. It allows me to provide students with appropriate reading material for potentially inappropriate topics, and I appreciate that. ( )
