Mercury

I lost count somewhere around "Oceans" or "Dogs," but this has to be Simon's millionth book. Either way, there's no arguing that this guy can write some great material for kids and even adults (who have kids and are smart enough to read with them so they don't grow up illiterate). I doubt Stephen Hawking read this book and had some amazing epiphany, nevertheless, this entire series of planet books is perfect for grade school through middle school science reports and projects or even if you just want to learn a bit more about what's out there in our universe. Full color and page-sized photos only add to Simon's academically written text that truly gets kids into science and into wondering about the world about them.
