High school senior Kate Winthrop is about to find out just how much she's worth. After stumbling across the Millbank Social Stock Market, Kate is horrified to discover that out of the 140 girls in her class, she's ranked a bleak 71. Sure, she's not drop-dead gorgeous, and her "fashion" choices leave a bit to be desired...but 71? Determined not to accept her fate as a "junk bond," she and her best friends quickly set out to make her the fastest rising stock on the Market. Armed with a sexy new haircut and killer wardrobe, Kate puts her plan into effect -- and the analysts take note. In a matter of weeks, her stock value soars, and "Blue Chip" status is within reach. But what begins as a fun social experiment quickly turns into an obsession, one that threatens to ruin her reputation, friendships, and a chance at first love. Will Kate survive the highs and lows of the Market, or will her security crash and burn?
