This was the Academic Sports League Decathlon book when I was in 8th grade. I actually began reading it, but then quit because it wasn't the book us Pentathlon kids were supposed to read. xD
It's not something that I would pick out either, but it was interesting to me. I liked the narration, though it was more passive than what I usually read. The kindness of the husband (sorry if I don't know the names or the all characters) made me somewhat touched; I expected a harsher family. I also was pissed that her two oldest sisters got extravagant weddings or whatever, and she got hardly anything worthwhile. :/ Except her kind husband. :3
Sorry I can't give a deeper response; I haven't looked at the book (which I hardly read) in the first place for a couple years.
