The Sisters in Crime blog has an interesting four-part series on the state of the mystery/thriller market. The writers visited a number of major publishers, agents, and publicists and asked questions about the markets and how to promote and build a career.
Most of the information is about the mystery/thriller market, but the blogs are well worth any writer's reading for the information about promotion and building careers.
The entries are in the final days of May.
