This started off quite promising, but ended with far more sputter than luster.When I noticed I was 3/4ths of the way done, I had no idea how this was going to be wrapped up. I really should not have worried, as it simply was not. It ended on essentially a cliffhanger, but unlike nearly every other YA book needing to be a trilogy, Goodman writes at the end, in an author's notes section that she likes ambiguity, ending with more questions than answers. To this I say "hmmm" and "phfft".To me this is easily a part one of a much greater story, but for whatever reason Goodman leaves it up to you. (Did she only get a one book deal? Was she worried that it would not be successful and was hedging her bets? Does she just like to taunt her readers?) I found this as lazy as her 'deus ex machina' style reveal of the, well for lack of a better word, rebel leader. I might nor have minded it so much if things did not seem so rushed at the end, as it made her writing fall apart. What was once crisp, clear, effective prose, becomes fragmented and spotty. Like many other YA novels, this is a story of oppression and how a young adult figures out how to overcome it, well at least it trends that way, with the lack of an ending, you are not quite sure if she did overcome it. And that is the main problem. To her credit, Goodman creates a compelling world on a drowned earth with only a few island land masses left. And I initially fell into reading this quite swiftly. That she opted to sandbag her story by stopping it rather than ending it really interfered with that enjoyment.
