It's obvious that Hope Larson was watching Sailor Moon when she wrote this. As an homage to the magical girl genre, Who is AC? is fun enough. Lin, our magical girl character, is a great character. I like her passion for writing, and her family is loving and attentive (always nice to see in YA). This is essentially a lengthy pilot, so there's a lot of setup and little payoff. If there's going to be more AC volumes, that will be fine, but if this is it, it's kind of disappointing. There isn't much to say about the overarching storyline setup here, because it's fairly standard magical girl stuff: shadowy villain controlling from the sidelines, with the monster of the week transformed from a person the hero probably had contact with before.
There's a message here, to be mindful of what you post online. I can get behind that, in general. But I'm not thrilled with the execution. The first person to really run afoul of that is a girl who posts a heartfelt expression of grief online. And I don't think we need to be going so far that we're telling people they can't put on their Facebook that they're sad about something. The flipside of that is Trace, budding cyberbully. Obviously, what he posts about AC is hurtful to her, but I have a feeling that complaining somebody stopped an armed gunmen from robbing a store wouldn't make Trace the most popular person online. He's almost cartoonishly jerky, is what I'm saying, and with an actual villain, I'd rather do without him.
The art is ok. Some pages are really nice, but some are just not up to the same standard. I like how the book is black and white, except for AC's purple. It makes her stand out like a magical girl should. I'm also disappointed in the cover. Why make Lin white on the cover when she's biracial inside?
