I just received my contributor copies of a new how-to book for aspiring mystery authors titled Now Write! Mysteries.
I knew a few of my friends were also contributing essays, but my eyes popped when I opened the book and scanned the table of contents. It seems like every mystery author working today has an essay in here, from A to Z - Emily Arsenault to Elizabeth Zelvin, to be more specific. The essays cover topics ranging from research to revision and everything in between, and many include exercises.

Oh, and I guess I should mention that my essay is on writing emotion. I re-read it - I think it's pretty good!
