Bag of Bones

The title, Bag of Bones, allude to a quote by Thomas Hardy;

'Compared to the dullest human being walking on earth, the most brilliantly-drawn character in any novel is nothing more than a bag of bones.'

The protagonist then adds: 'The only problem is that sometimes I feel like nothing more than a bag of bones myself...a bag of bones without the energy or talent to do what I thought I was born to do.'

Thus, we can infer the main character is alluding to writer's block he's suffered since the death of his wife.
