Fun with Google book search.
In the end, I wished that I had resisted. The book was terrible. The heroine was boring. The love interest was annoying. The phrase "taut nipple" was way overused.
So I looked it up on Google book search and got 450 results. Sherrilyn Kenyon isn't even original.
My favorite is this one, from Forbidden by Elizabeth Lowell:
“Aye,” Duncan groaned, brushing his mustache over one taut nipple. “And aye —he brushed again—”and aye, and aye one thousand times more!"What is it with Scottish people and romance novels? Those rugged kitled men get all the action.
