I've read the two previous volumes, which aren't obligatory but it's probably advisable to read the work in order. It's hard to know why Knausgaard's series is so gripping, but it is. Here, he recounts his childhood on an island. Nothing super-dramatic happens, but the narrative carries you along. His relationships with his family and friends, sexual awakening of a sort, all these are described, as well as the rather strange, isolated environment in which he's brought up. The whole series has been highly praised and in my view deserves the praise it's been given. Let's hope we English-speakers don't have to wait too long for the rest.
