It is quite difficult to put into words how utterly appalling this "advice" book is, but I'll try my best.
To start, this book is written by a man. Sure, he claims he has help from his sisters, but that doesn't take away from the fact that most of this content is his idea. He does, however, have an advice book for boys (The Big Book of Boy Stuff). A man writing a book about and for girls is unheard of for me. Bart King doesn't know and will never know the experiences that women and girls go through. Readers have to be at least eight years old to dive into this book.
Before I delve into the individual sections, I'd like to note that this book is very hetero-normative across the many chapters. Bart writes that a girl crush is "adoring a super cool girl in a platonic way" and when explaining the Irish Claddagh ring, it means that the wearer (a female) has a boyfriend. As an openly bisexual person, it is sounding as if Bart is trying to cover up the existence of people in the LGBTQ+ community.
Now, onto the first problematic section: Boys. It goes into detail about what you should do if you have a crush on a boy (because again, hetero-normative), like keeping it a secret from your friends so they don't "steal" him and finding a magic song to remind you of your crush.
The Boys section also talks down heavily on boys, saying they're "sooo immature" and that they hide their feelings. Additionally, it includes stereotypes about what a boy's personality could be based on what he wears and what his hair looks like. This segment also discusses what happens during a breakup; a "term" called breakup-rexia. It's supposed to be a play-on-words with anorexia, but it can feel very invalidating to those with the eating disorder.
The next section I will be breaking down is titled Slang. Out of the entire 320-page book, this has got to be the most absurd and preposterous portion of writing. It includes words like "bitchin'" and "bohunk", just to begin with. Many rude names are involved, such as "aristo-brat" and "prat". Thinking back to "breakup-rexia", there is also a title written down called "tanorexic", which is "a girl who has a tanning disorder. She thinks that she's too pale, and so she tans constantly." Anyone with common sense would know not to call anyone these horrific names.
A couple of points are noted where the author invalidates mental health, including that a "sadaddict" is "a girl (maybe a Drama Queen) who is hooked on feeling sad." It puts having a phobia or just having anxiety in general into air quotes as a "mental health disorder". Many of my friends and I have mental health issues, and this just adds to the stigma.
Throughout this book, there are mean comments and pranks advised to do to your friends. A "Mean Cheer" talks about murder and mutilation, while a "prank" a girl can do to her friend is putting instant mashed potatoes onto her lawn to spell out an embarrassing message. I couldn't believe what I was reading when I saw these since they are the complete opposite of what anyone should be saying and doing.
When I saw the Girl Emergencies section, I assumed it would talk about real emergencies, such as what to do if there's a fire. But instead of talking about worthwhile things, it advises girls on what to do when they're in public and don't look their best and they see cute guys from school. It also discusses what to do when you don't have anywhere to sit for lunch and have unstoppable hiccups. These situations are not actual emergencies. This section just couldn't be more disappointing.
My final point is on the inappropriate content in this book. King writes, and I quote, "You can sell anything you want with breasts." The book also talks about waxing your legs, making a fake belly-button piercing (and using Elmer's glue to stick it onto yourself), liposuctions, and botox. Eight-year-olds should not be reading this type of content at their age.
In conclusion, this book is not worth the $15.00 it sells for. These are just a few of the many ludicrous instances I scanned, and I advise you not to buy it. If you're looking for alternative advice books, I highly recommend American Girl's "A Smart Girl's Guide" help books, available wherever books are sold.
