Women Don't Ask and Ask for It are two books on women and negotiation by Linda Babcock and Sara Laschever.

In Women Don't Ask Babcock and Laschever describe both various reasons why women are less likely to negotiate with employers, partners, colleagues and businesses than men are, including negative responses to appearances of assertiveness in women and women's tendency to believe that they will be rewarded fairly for hard work; and then show how not negotiating hurts women's salaries, careers and personal lives. In Ask for It they teach women negotiating skills.

The books are not focussed on geek women, but have been widely discussed and recommended in LinuxChix by Valerie Aurora. One factor that recommends them to geek women is their solid research grounding.
