I'm not really into superhero comics, but was excited to see a new female superhero. Also, it was written by Chelsea Cain, who writes the bestselling Archie Sheridan/Gretchen Lowell series. If you have not read this series you I'll let you know it's about a psychopathic female serial killer. So basically "Mockingbird" is about S.H.I.E.L.D. agent and former Avenger, Bobbi Morse, as she goes on a few missions, from deep sea diving to uncover a secret nuclear facility, to saving her current boyfriend from an underground gang. Bobbi has super powers because she is part of a government experiment which is also causing her mind to hallucinate.
The story-line was fair, but again I'm not really into superheros fighting bad guys page after page. I do like that she is a strong female heroine with personal and mental issues like everyone else.
The writer Chelsea Cain cancelled her twitter account after receiving a lot of harassing tweets from male comic book "fans" commenting on her pro-feminist stance, which really only makes me want to recommend this book even more!
