I felt this as a very informative read. Let me go step by step into this review because, despite the fact that I liked it a lot, I had some issues as well.
"Period Power" is really what it promises: a book about periods and it can be read by a very large audience, from those who mestruate to those who don't, from young people to old. The book starts by explaining what is a period. Is a simple explanation but I felt it might be useful to start the conversation with young children/pre teens, making them more aware of body changes. The book is very US based, reason why I ended up skipping part of two chapters, which I usually don't do. Chapter 6 and 9 were the ones, 6 being very focused on state policy on periods that doesn't really apply to my reality here in Europe and 9 being very focused on US activism on periods (I end up skipping parts for the same reason).
I felt very privileged while reading about homeless women and incarcerated women. For me, this was the most educational part of the book and for this alone I would totally recommend reading.
The book also addresses some important topics like the difficulty in accessing period products and the necessity in making them free. I believe it already is done in some countries, but again, very US based so we don't get that sense.
The author is really inclusive towards people who menstruate, which I felt very important. However, I felt the narrative was not always very inclusive towards all of menstruation experiences. There are some mentions of period pain, for sure, but the majority of the book makes us think that the main issue is the access to period products. I won't say it isn't. I can't even begin to imagine the day to day life of people who lack the access to these necessity itens. Nevertheless, every menstruation experience is different and pain can truly be a pain in the ass (pun intended!). Pain and discomfort during periods are real and people should not have to carry on with their daily lives as if nothing is wrong. I would have liked to see more discussion on menstrual leaves, which some companies already have. I have mixed feelings on those, so I would have liked to see them deeper explored.
Finally, I could not end without mentioning some wrongs in the book: female cycles don't synchronize! I just wanted to roll my eyes at this! I mean, I'm not a trained professional on the subject, but, from what I've been reading, this is just bullshit (pardon my french!). The cycle is not 28 days for everyone. It can be longer, it can be shorter and it's dangerous to continuing spreading this idea that is 28 days (thankfully, it didn't say that ovulation occurs at day 14! which, as a matter of a fact, doesn't for everyone). Then, there is no such thing as "chemical free materials" as everything is made of atoms (as I chemist, I just couldn't let this one slide trough).
