Battle with the Bugs, Human Body Detectives series, $16.50
I've had the privilege to work with Dr. Heather Manley in helping promote her Human Body Detectives series of workbooks and CDs. The second book, Battle with the Bugs, has only been out a little over a month, and it's already a hit with kids everywhere. In this book, Merrin and Pearl travel inside their cousin Max's body, where they befriend a white blood cell warrior and help fight invading bacteria who are making Max sick. The CD includes a narration of the book, and the workbook includes tons of activities for kids to do while following along with the story. The full-color stickers included are super cute and provide more fun for kids. Right now you can even order an organic T-shirt that says, "I fought the bugs and I won" to go with the book.

Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 1: The Night of the Nasty Nostril Nuggets by Dav Pilkey, Amazon.com, $5.99
Does this book have "boy" written all over it or what? It only makes sense that a man, Dav Pilkey, is the mastermind behind all of the Captain Underpants books, because I honestly don't think a woman could write these. I read this book to my boys, and I literally gagged in one particular place. For real. But I still love these books; they're clever, funny, and the epitome of "boy humor."
