There are some novels that tell a great story and others that make you change the way you look at the world. Chimamanda Ngozi Adichie's Americanah is a book that manages to do both.
It is ostensibly a love story – the tale of childhood sweethearts at school in Nigeria whose lives take different paths when they seek their fortunes in America and England – but it is also a brilliant dissection of modern attitudes to race, spanning three continents and touching on issues of identity, loss and loneliness.
