I'm actually Enders Game right now (don't want to read only Discworld for the remainder of the year
) and it's just that great book to lose yourself in. I almost finished it and started yesterday
About the Discworld earlys, yeah the writing isn't that polished, and the story and characters have hardly any depth...but they are soooo funny. I hope the writing stays at least close to being this funny throughout the series.
