In Book 2, we meet the peoples on the other side of the world of the series, and learn what they do with the quota and why. We also see what has become of the surviving Akaran children, and how they have grown into adults. I won't spoil anything for anyone, because it's a lot more fun to experience the story on your own.
I highly recommend both this novel, and the 1st book in the series, Acacia, to anyone who likes Fantasy. Check these out.
Ten +++ out of ten.
