Don't Tempt Me by Sylvia Day

SOMETIMES TEMPTATION . . .
A hardened mercenary as adept in bed as in battle, Simon Quinn can have any woman he wants, but he prefers those who know the rules of the game. That way it’s easier to leave them behind . . .
 
CAN’T BE AVOIDED
But Lysette Rousseau is one female he can’t figure out. Beautiful, sensual, seductive, she should be the perfect match for Simon, yet something about her ties him in knots. Bold and manipulative one time, sweetly innocent the next, she is an enigma bound to bring trouble . . . impossible to resist.
