Query: Borrow the library copy and read 50 first pages ONLY

Dearest Gary, I am sure you are aware that your book lost its steam after 50 pages and turned into boring, jejune, vacuous multitude of silly pages. It could make a nice novelette or a story. Consider writing short stories, with the intensity and panache you have invested in the beginning of this unfortunate book. Now that your coffers are full, you can try to REALLY write thoughtfully and deeply.Waiting.
