He taught by the book. She never followed the rules. When 21-year-old Aria Eloise steps into Professor Kian Heyness’ history class, the last thing she expects is to be distracted by the one man she absolutely shouldn’t want. Cold, brilliant, and infuriatingly strict, Professor Heyness has zero tolerance for trouble—until Aria becomes his exception. One misplaced paper. One late-night detention. One quiet, “Yes, Sir,” and suddenly, the line between discipline and desire starts to blur. Behind closed doors, their stolen moments grow harder to ignore. But the walls of academia are thin, and secrets don’t stay hidden for long. Because in his classroom, he’s in control. And Aria? She’s about to find out that challenging the rules comes with consequences… and sometimes, they’re exactly what you’ve been craving.
