All right, I've made it.
The book is divided in two parts :
Part 1, chapters 01 to 48 (currently still missing chapters 45 and 46) is called Glasses & Pulleys
Part 2, chapters 49 to 81 is called The End of Bread
Part 2 is complete, I've managed to proof-read everything.
Here are the files to "The End Of Bread"
The complete novel is now over 413,000 words long, once the two missing chapters are finished it will about 420,000 words long.
It has been a tremendous experience for two and a half years. Please provide your feedback !
