+writers whose initial contact with me was by a query letter in the incoming mail (fondly known as the slush pile)
## second novels by writers for whom I also sold their debut novels.
I'm now going to leave the query letter ranting to others. The bottom line for me is that the query system in place now works just fine. I find great clients there. I sell their work. I may miss good stuff, but I'm ok with that.
