Thanks to Hachette, I can offer up five copies of 7th Heaven by James Patterson and Maxine Paetro. 7th Heaven is part of the Women's Murder Club series.
Here's the publisher description:
"The Women's Murder Club faces not one-but two-terrifying cases that may tear it apart. The teenage son of California's ex-governor has mysteriously vanished-and the pressure on Detective Lindsay Boxer to find him is overwhelming. When she finally does get a lead, it's devastating. At the same time, Lindsay and her partner, Rich Conklin, must investigate mysterious fires that are destroying some of San Francisco's most beautiful homes-and leaving their owners dead in the debris. But when Lindsay enlists her friends in the Women's Murder Club to help uncover the arsonist, the blazes suddenly rage much too close to home."
