The Silver Six - AJ Lieberman

For a kid's story, it starts with the murder of a bunch of families by a corrupt energy company. Eventually, Phoebe, her robot pal, and 5 other orphans band together to discover the truth behind what happened and fight to set things right. It's not a bad story, although because it is for kids there isn't a whole lot done in terms of characterization other than the smart guy wears glasses and the the brown kid is brown (Darren Rawlings' art is a great deal of awesome, though). I do like the empowering nature of the tale and it has a couple of minor twists to help it along.
