Second chance to make a first impression?

My chosen agent, Camilla Bolton of the Darley Anderson Literary Agency, came back to me with a rejection on Saturday. However, the letter she sent wasn't the standard 'thanks, but no thanks'. It was a most complimentary and constructive acknowledgement of The Messenger. Camilla made suggestions as to how the story (which she thought exciting) could be improved by cutting portions of chapters and making a couple of other alterations - in general, it was obvious that she had spent time reading and inwardly digesting my story. I emailed her to say I was going to incorporate the changes she had suggested and thanked her for her time. I also acknowledged that the road to mainstream publishing was a tough one, but that I was determined to succeed. This morning I received an email from Camilla to say if I was willing to make the alterations and, if I wanted to re-submit to her, she would not only be happy to reread it, but would be happy to read anything else I write. What a brilliant lady! Obviously, there is a god after all.
