I enjoyed Ender's Game, but thought the remaining books in Ender's Saga were a little weaker. Still enjoyable to read but not as gripping as Ender's Game was. I've found the same with the Shadow Saga too, Ender's Shadow was just as good as Ender's Game, yet the remaining books in the saga haven't been as good. I'll be starting Shadow of the Giant soon, which is the last in the Shadow Saga.
I'll have to get Ender in Exile now
What's the Homecoming series like btw? Seems to have received mixed reviews, so I'm not sure if it's worth buying yet.
