I've been slowly reading my way through this thread over the last couple of hours (not read every post here yet - there's a lot). There really is some excellent advice here, and it's refreshing to see an agent so willing to take questions in this way and give such honest answers!
I just wish that I had known about this site and, in particular, this thread before submitting several books over the last couple of years to you. I read with reddened cheeks a few of the Mickey Mouse mistakes I made (and I have the emails to go back and cringe over too - I just did that).
At every level though you were the most helpful, amiable and polite person I ever dealt with in publishing, despite my falling into several of the traps you have warned against in this thread. I did take all you said on board, and it has gone to make my writing far better than the amateur rubbish I used to send you
I didn't realise that Alfred Bester's 'The stars my destination' was one of your favourite books otherwise I wouldn't have dared suggest that I might have had a slightly similar writing style. Still, it was an influential book.
Thanks for all the good advice!
