The Humans by Matt Haig

An excellent book which I really enjoyed. Professor Andrew Martin is taken over by an alien life form seeking to destroy the evidence of a mathematical breakthrough which the Professor has discovered. The plot gives a platform for a wonderfully humorous, well observed and thought provoking book about the behaviour and social conventions of humans. The writing is good and easy to read, but it is the delicate observational dialogue and plot twists which I really enjoyed.  A great book.
