I read this issue today, and while it's waaaaaay outside of Marvel continuity, it's quick a fun little read.
This is, basically, the female Avengers in high school. We've got Janet Van Dyne (Wasp), Jennifer Walters (She-Hulk), Carol Danvers (Ms. Marvel) and Namora (um ... Namora.)
The story, while nothing ground-breaking, is fun. What happens when you take well-known female superheroes, turn back the clock, and toss them all into the same high school? Chaos, of course!
The art on this book is very cute, and suits the story and subject matter perfectly. It's a little bit Manga, and a little bit cartoony, and all-together cute.
I think that younger readers, especially girls, would find this issue very attractive. I myself am a middle-aged male, and I enjoyed the book, so it's good for people of all ages.
