Based on a short story, one of Asimov's favourites, which I have not read (but would like to... ).
First read (late 2007?)Edit
Read it in second year of uni, Emma read it first I think. An interesting book about a young neanderthal (I think) brought through time to the modern day and raised as a scientific project, and the implications of the balance of his similarities and fundamental differences to modern day humans.
