Okay, I've read through volume 4, and I'm giving up on this series. It was interesting enough to want to find out what happened, but not enough to keep me reading beyond what we already had checked out from the library. I do not recommend them. I haven't liked the dynamics that have been emerging in volumes 2-4. I'm not saying every character has to be nice, or even nice all the time, but I wasn't happy with one character being abused (hit, talked down to, kicked, etc.), and the other character just taking it and begging for the friendship to continue. I know it's part of the plot and characterization, but it just made me upset that they acted like this and that the one didn't stand up for himself enough. It is not okay to be treated like this. Ever. Yes, it happens in real life. I get it. It just makes me more angry to see it in literature. It's left for the readers to judge as the relationship is show without commentary or bias, but since I won't stand for it in real life, I won't in literature either.
Because I was pre-reading this series for my almost 12 year old who loves manga, I was uncomfortable with the same-sex relationship innuendos that were introduced in volumes 3 and 4. It's not that I'm homophobic or anything. I just don't see it necessary to the plot (unless this is the focus of where the plot is heading, and if so, my son is too young for these themes). I won't be encouraging him to read this series.
All that aside, I did enjoy the references to classical literature, especially Shakespeare. And I enjoyed the art work.
