The Adventures of Superhero Girl
Faith Erin Hicks
This unexpected treat I found in the children's section of Cardiff Central Libraries, during a day I spent "researching" the resources there. (I was finding materials for story time and got distracted in the graphic section.)
Superhero Girl is a completely terrible superhero, especially compared to her brother, who takes on the world and handles the fame of his status with ease and composure.
And yet it is Superhero Girl that I would like to be - terrible with romance, impoverished by lack of income, and pretty useless at maintaining her secret identity. Her missions are somewhat mediocre - rescuing cats from trees, placating her overzealous mother, etc. - but that makes it all the more brilliant when her arch-nemesis finds himself chosing between continuing in a career of evil and a more conventional profession.
This comic stemmed from a blog, which you can find here: http://superherogirladventures.blogspot.co.uk/; and author Faith Erin Hicks is very vocal and entertaining on social media. She is definitely worth following.
