This debut novel by New Zealander Beckett presents us with a post-plague world where an island colony of uninfected humans guards its health and resources ferociously.  But all is not as it seems.  An unique format and tight writing make this science fiction gem open to second and third readings.  Some elements of the story may be predictable to those readers immersed in sci-fi, but I found myself engrossed, surprised and reminded of my old favorites Bradbury and Asimov.  An especially good choice for middle- and high-school readers.
