Flight Behaviour by Barbara Kingsolver

This is a strange book about a young American couple and their two children who discover a migration of butterflies on their land.  Their lives are taken over by the flock of visitors and scientists who come to investigate, and this impacts dramatically on the family's hierarchy with life changing results.  This is nowhere near as good as either of her other two novels I have read, partly because the plot is a bit thin but mainly because the writing is not as poetic or meaningful as in her previous books.  I did enjoy the characters, particularly the mother of the two children who is very well developed and realistic, but there was not enough overall depth to the book which made it quite boring in parts.  It did not help that this is a long book because this really stretched the subject matter to breaking point.  It is an interesting read but does not reach the standards of her previous books.
