quality and a broken promise

I made a recent (ish) announcement that I would be releasing a book on my birthday, Jan 26th, and I want to say that to date it is the most amazing thing i have ever created. It is well written, suspenseful, and I am sure  that it will leave anyone who reads it pleasantly uncomfortable. Unfortunately it is not complete and I feel like I would be cheating both myself and you to release it right now. 

I have known for a few weeks but I was hoping I could somehow pull a magic trick out of my hat and meet the deadline and I have failed to do so. 

I will keep you updated. Thank you so much for your support.
