i finished So Yesterday yesterday and i was personally not all that into it. I didn't pick a character as my favorite(which i usually do within the 40page area) until the end when i readized that Jen wasn't so bad. Overall i thought it was good, but not as good as some of Scott Westerfeld's other books. It was still better than some other books i have read before though, such as Wee Free Men by: Terry Pratchett. That book was pointless. On a scale of 1-10 1being the worst and 10 being the best i would probably give it an 8.5.
P.S. If you have a different opinion and you really hate mine, keep it to yourself please!!!
