Untouched Queen by Royal Command by Kelly Hunter

He must choose a queen... But will his desire outweigh his duty?

King Augustus is shocked when his country delivers him a courtesan. The only way to set her free is to marry someone else! But Sera's surprising innocence and undisguised yearning for him is temptation itself, pushing Augustus's legendary self-control to the limits. Because Augustus knows that if he dares give in to his attraction he won't rest until Sera becomes his queen!
