Who's That Lady — Andrea Jackson

Crystal Taylor has been best friends with Kay and Shonte Emerson since high school. The siblings have always relied on her practical guidance to keep them on track. But suddenly everyone seems to have lost their mind. Shonte is in hot pursuit of a married man and Crystal and Key stumble into an impetuous one-night stand.

Key Emerson is confused too. Levelheaded, reliable, bland Crystal has changed her look from business exec on the rise to hot squeeze who makes a man weak in the knees. In bed, she's wilder, sweeter, more fulfilling than he dreamed a woman could be. He could always talk to the old Crystal about anything. So why doesn't this new Crystal want to talk about a relationship with him?

Crystal doesn't understand how her body can betray her sharp, logical mind this way. There's no way anything permanent can come out of this purely physical indulgence with Key. Crystal was always the one that everyone came to for guidance. But now she doesn't know the answers. She doesn't even know who anyone is anymore -- including herself! Will love make her lose her two best friends?
