I'm currently with Silence in the Library. My first book Vision of Shadows is out through them. And they contracted me for the entire series. (5 books total) the 2nd of which comes out in February.
So far I've been very happy with them and have enjoyed working with everyone I've had contact with. There are 2 friends of mine that are also authors with them, one came out with their book before mine and one is being released soon. Both of them seem to feel the same way.
Just as an example, when it was time to come up with my cover, there was a lot of back and forth. I had a concept that I really wanted to use, and they made every effort to try and make it work. (And they really tried hard.) However, we couldn't get it quite right. The artist came up with a new design and although different, it just seemed to work really well. I made a few suggestions and it all came together. But at no time was I told that I had no input. My input was not only welcome but sought after. You can see it down below in my signature and as my avie.
I had a choice of 4 different publishers to go with, but I feel I made the right choice with SITL.
