We all know that often, sequels don't work as well as the original. here ... that just doesn't hold.

Varley's taken the idea behind the first story, forwarded us on to the next generation, and thrown complex, relevant and timely issues into a pot and bubbled them all up into a fantastic, readable adventure. I'm still a little disappointed at how long these teens take to open up to their feelings, but perhaps the more cautious nature is warranted in such a dangerous time. The ending paves the way neatly for any future works (of which I think there are at least two, so that should keep me happy).
