Girls vs. Guys

The differences between the sexes have been around since time immemorial but some are based on biological fact and others are not. In this visually stunning and humorously accessible book, Rosen introduces children and teens to popularly held beliefs about women and men and provides research-based support or opposition to what they claim as truth. Each chapter is a succint two page spread and concludes with a take-away or summary of the chapter's main point. The book also does a great job of impressing upon readers, without being pushy, that gender is considerably more fluid than the binary system most people consider it to be. The back matter contains a diagram of the brain with labeled parts mentioned throughout the book, source notes, a selected bibliography, books and websites for further reading, and an index. While it would have been helpful to have a glossary for the different parts of the brain mentioned, it's not essential. Sexual intercourse is hinted at or mentioned a few times but isn't graphic or specific enough to warrant concern for younger readers picking this up.
