Ok, VERY cliche question, how about everyone's favorite book this time? : D
Mine's probably Sealed with a Diss. It's a particularly dramatic one, and I thought Skye's presence made things interesting. There's a note of melancholy too, with it being the end of 7th grade.
Another fav is The PC strikes back because it's a classic and there seems to be equal focus on everyone in the clique-everyone gets their own unique story in this one. I thought the Massive/Derrington story was actually kind of sweet, and the Cam/Claire story as well.
Wbu?
