15 Books That Can Help Explain Menstruation to Tweens

The authors of Bunk 9's Guide to Growing Up: Secrets, Tips, and Expert Advice on the Good, the Bad, and the Awkward ($8, originally $13) recommend that parents read the book before handing it over to their child so they're prepared for any questions that may come up (and they definitely will). The book is written from the perspective of a group of camp counselors who have been through everything your child is about to go through and want to help make the transition as smooth as possible.
