Brutally Beautiful - Symbiotics, #4

Nick Taylor, poetry lecturer, used to be Mick O'Donnell, British gang leader. In search of a new life he's come to New York, and five years later, he's nearly there. He's kept clear of trouble, under the radar except for his visits to burlesque club Bared, and it's there he meets his nemesis. Beautiful, classy, irresistible. Trouble. Nick is unlike any professor Gen has ever met. They can't keep their hands off each other, even in the university library.
Much less in the all-glass room in his apartment. Nick teases her with the total exposure she secretly craves, while always keeping her safe. But although Nick needs to draw on all his resources when Gen finds herself in deep, unexpected and deadly trouble. It might end his clean start, but if he doesn't risk all he's worked for, and draw the kind of attention that could mean his death, the woman he's grown to love will die.
