I adored this graphic novel. The illustrations are absolutely beautiful. They're all in monochrome purple, which makes it moody and a little mysterious even in the bright sunshine. And they're so exquisitely detailed, just, GOD, I LOVED THE ART IN THIS BOOK!!! 
 It fit the story very well, I think. Rose and Windy are growing up and they're just now discovering things about their bodies, babies, and physical relations. It's not graphic in any way, but I'd probably recommend it to an older teen. Themes in this book include friendship, growing up, and trying to hold onto your childhood.
