This book reminded me of David Levithan's YA stuff, in these girls are way too smart and well-spoken to resemble real teenagers in any way. They all talk like they are in a graduate level women's studies seminar at all times. Which is fine–I love reading sassy teen girls talk about representations of sexuality in hip hop. (I love David Levithan's overly-educated teenagers, too.)
The friendship between the members of Sister Mischief, an all-girl hip-hop crew in suburban Minnesota, felt realistic, even if their dialogue didn't. Their dialogue (and raps) are hilarious and heartfelt.
