I could just not post anything more about this process but I guess since I started it I feel a little obliged to continue, so this is an update.
Anyway, this CEO and literary agent read my manuscript and sent me a very thoughtful email beginning with, "There is a lot to recommend it but it's such a tricky subject that a writer has very little room to maneuver if it doesn't exactly nail it. And my problem is I think this is a great effort, and the writing is good, but it's overplotted and its tone is somehow "off" to be honest."
Is it my ego that made that sound positive to me? I understood, tho, that he doesn't think he can sell it. He kindly spent a lot of time writing several paragraphs with suggestions on how to improve it. Which I so appreciate. The thing is I've worked on this book for so long that I don't think I have the energy for a(nother) rewrite. And (here's my ego again), it's only one opinion. One I trust, but still...
