More than half of all paperbacks sold in the United States are romance novels. But romances are far from just the girl-meets-boy, girl-loses-boy, girl-gets-boy-back formulas of the past. Some romances are sweet, even inspirational, while others are very, very spicy. Some are set in the present, others set in the past, and a few are even set in the distant future or in faraway galaxies. So, what makes a romance so appealing? You might be surprised to find that it's not what you think.
