A story about crushes, conflicts and astrological confusion. Finally, after years of making love predictions for her friends, fifteen-year-old astrologer, Emma Seigel, sees a boyfriend in her future. But there's one big problem. Mercury is heading for Retrograde in four weeks, and she sure knows what that means. It's like an astrological PMS. A disastrous time to start a new relationship. Using her school newspaper column, Emmastrology, she sets a plan in motion and within a week lands hottie Evan Randolph as her boyfriend. She's a Taurus.

He's a Capricorn. Both earth signs. What could be more perfect? But is he as perfect as her prediction claims him to be? The stars are telling her it's right. But her heart says it's all wrong. Everyday her feelings are growing stronger for someone else, a Leo, so totally not the sign for her. And to make matters even worse, Emma's actions, caused by her unflinching belief in astrology, get her in trouble with her best friends in the whole world. Time is running out. Can Emma straighten up this mess she's in before Mercury goes Retrograde again?.
