If you know how to read it, your hormone cycle can be your formula for success. With 28 Days: What Your Cycle Reveals about Your Love Life, Moods and Potential, you can learn to forecast your life and plan your schedule day by day according to the ups and downs of your monthly cycle.

As easy to read as a horoscope, but based on science, 28 Days helps you tune into your internal calendar and take charge of your life. You'll know when to ask for that raise, wink at the cute guy at the coffee shop, or just stay home in bed and eat chocolate.

Nationally-known women's health journalist Gabrielle Lichterman also provides quick tips for dealing with the moods and challenges that can strike—from eating iron-rich foods when you're low on energy to amping up your sex appeal when you're feeling frisky.

A hip, helpful, and humorous guide, 28 Days is a must-have for women everywhere—enhancing and empowering our lives each and every day!

28 Days has been featured widely on TV (including ABC, CBS, NBC, FOX and the BBC), in print (including Cosmopolitan, CosmoGIRL, Glamour, Ladies' Home Journal, Marie Claire, Self and Women's Health) and on radio worldwide and was named one of the top women's health books of 2005 by About.com.
