Beyond wonderful. Please read this book. 5/5.

 In case you don't know anything about Achilles' story, I will keep the following deliberately vague. 
 This is a beautiful book. I lack the vocabulary to do it justice. 
 The Song of Achilles is one of those rare wonders: a narrative which weaves a world around you which is so rich and compelling you don't want to leave it. It doesn't matter if you know everything or nothing about Achilles because this imagining is original. We are given an intensely personal, insider's view of events which are usually the distant stuff of legends: Achilles' boyhood and the Greek siege of Troy. 
 Almost the entire story is told by Patroclus, Achilles' companion. We watch him and Achilles as they grow from young boys to men, and their relationship forms the core of a story around which orbit gods and goddesses, dryads and centaurs, kings and warriors. 
 It took Miller 10 years to write this book and I can see why: the result of her hard work is practically perfect. 
 Overall: you know you've read a 5* book when you finish and would dearly love to go back to the beginning and read it again straight away. One warning though: while this is beautiful, it's also heart-rending stuff. Probably best to wait until you're in a happy place to read it.
