Girl Genius Vol. 1: Agatha Heterodyne & the Beetleburg Clank by Phil Foglio and Kaja Foglio
Agatha has been trying to build awesome steampunk machines, or well to be more exact she's been trying to build ANY steampunk machines. Much to her chagrin, however, she hasn't been able to make anything that's worked. Then things explode. There are a lot of explosions.
The first volume of this series is not actually that good. To be honest, it was somewhat boring because of the time spent setting things up. It's like rating a book if you've only read the first 3 chapters. It might be interesting, but it's probably not all that exciting.
Agatha has promise to be a very amusing character. The steampunk has promise to be pretty awesome, and I'm looking forward to explosions. Thus, I will continue to read this series because it has promise. This first volume though, don't expect it to really blow your mind away unless I'm missing something crucial.
