The third book: #3 The Tale of Genji
This is a long book - I'm just over halfway through and it feels like it has taken ages to get this far. The book is fairly dense, with a lot of cultural reference you're just assumed to know - I have to keep checking.
What's interesting is how, although Genji is the main character, he's not a hero. He cheats, has affairs, abandons his wives and isn't too happy with his children so far. It makes for a compelling story, but also an interesting indictment - you are meant to sympathise with the others, although as often they are inactive characters, unwilling to do more.
