5. The Children of Hurin, JRR Tolkien
Tolkien is one of my favourite authors, but I find he does require a lot of concentration! Unlike The Hobbit The Children of Hurin is not at all lighthearted with a happy ending. It is steeped in the mythologies, genealogies and histories of Middle Earth; the book comes with beautiful artwork, maps, family trees and lists of names and pronunciation.
This is not a 'new' story, much of it being covered in The Silmarillion, but in much greater depth. Morgoth, the first Dark Lord, takes revenge upon the family of Hurin as punishment for his his defiance. His curse follows his son Turin, blighting every decision he makes and poisoning all his relationships.
Although Elves, Dwarves, Gods and dragons feature a lot, this is predominantly a story of human emotions and imperfections where although the decisions they make are disastrous, we can relate to why they are made.
It is a tragedy of Shakespearean proportions. If you thought George RR Martin was cruel to his characters, he doesn't have a patch on Tolkien!
I need something much, much lighter so no moving onto The Devil Wears Prada, Lauren Weisberger
