Agnes Quill is a teenager who is just trying to make a buck. Having taken over the family business, she uses her special abilities to help the strange inhabitants in her steampunk city Legerdemain find what they're looking for. Whether you need to get rid of some ex-girlfriend zombies, keep your underground community connected to electricity, or find an expensive heirloom in a corpse's head, Agnes is the girl to solve your mystery. (It helps that she can see ghosts since most of her clients are dead.)
I liked this book quite a bit. It seemed very fresh even though it was published five years ago, I loved the steampunk traits mixed in with the mystery and Agnes was just so wonderful and funny. There were four stories with a different artist for each: Jason Ho, Dave Roman, Raina Telgemeier, and Jeff Zornow. I actually didn't really catch on until about 3/4 of the way through that the main character in each story was supposed to be the same girl, but it was still wonderfully done. I especially liked Ho's and Zornow's artwork, it seemed to really fit the setting of the stories. The others were good, but perhaps a little too simplistic. Regardless, awesome. Pick it up and give it a go. You won't regret it.
