My 8-year-old daughter and I share a love for Egypt. So she brought me home this book from the library.
I'm shocked at how much information they jammed into this 70-page book. Facts and measurements on the pyramids of Giza, plus lesser-known pyramids around the world (but mostly in Egypt, because that's where most of the world's pyramids are); facts about the men and women who commissioned them; general information about ancient Egyptian culture; and dates and general information surrounding the archeologists who discovered them. Each 2-page layout took me, I dunno, 10 - 15 minutes to get through. Fantastic!
I highly recommend this book for preteen kids interested in Egypt and/or pyramids. If they have a little bit of a geeky side (like my daughter), then they'll love the facts. If not, they'll skim those and love it anyway.
(Oh. If you or your kid would be squeamish (or too excited) about human sacrifice, then you might want to avoid this book. Or at least certain pages of this book. The Mayans used their temples for human sacrifices, and the book goes into mildly graphic detail about it. It was a little icky, even for me. Just FYI.)
