Okay, not actually a mystery/thriller, but some really interesting authors contributing to this freebie on Amazon:
MAKING STORY: TWENTY-ONE WRITERS ON HOW THEY PLOT (TWENTY-ONE WRITERS #1) (THE TWENTY-ONE WRITERS PROJECT)
It's often said that everyone has a book inside him or her -- but how do you plot it? In MAKING STORY, edited by the Edgar- and Macavity-nominated author Timothy Hallinan, twenty-one novelists--who have written more than 100 books among them and sold hundreds of thousands of copies--talk about how they go about turning an idea into a plot, and a plot into a book. MAKING STORY offers practical, experience-based advice from people who have repeatedly sat down to write a good book and succeeded in doing just that. The writers who will help you to create your story are Michael Stanley, Kelli Stanley, Yrsa Sigurdardottir, Jeffrey Siger, Zoe Sharp, Stephen Jay Schwartz, Mike Orenduff, Debbi Mack, Wendy Hornsby, Gar Anthony Haywood, Timothy Hallinan, Leighton Gage, Jeremy Duns, Bill Crider, Meredith Cole, Jeffrey Cohen, Rebecca Cantrell, Rachel Brady, Lisa Brackmann, Cara Black, and Brett Battles. This is an indispensable book for aspiring authors and the first in a series, each focusing on a different writing challenge.
