The Professor’s Secret Crush by Elana Johnson

She’s about to break her university’s rules and date a student… Come to the dark side, where the romance is still sweet.
Cassandra Caldwell wants one thing: to keep her twin brothers safe. After her mother’s death, she took them in and relocated to Forbidden Lake, where she’s done whatever she could to keep them off the radar of their convict father. She’s working two jobs, including as a culinary instructor at the local college, when she finds out he’s out on parole. As if she isn’t stressed enough, when a man enrolls in her special needs course and refuses to transfer out, Cassie wonders if she should just take her brothers and leave town. Again.
But she’s tired of running, and Jonathan Addler is drop-dead gorgeous—and good in the kitchen. But the college has had a recent student-teacher scandal and a relationship with him is strictly forbidden…at least if Cassie wants to keep her job. She does, but she also wants Jon, badly.
Jon originally signed up for the introductory cooking class to impress another woman and get one step closer to graduating to impress his father. But the moment he lays eyes on Cassie, he’s smitten. Any risk is worth being with her, and they agree to keep their budding romance on the down-low.
The way down-low, especially once Cassie gets notified that she’s up for a promotion at the college that would allow her to give up her second job. As she and Jon carry on their relationship behind closed doors, he falls harder and harder for her. But she can’t really commit to a relationship when she has emergency escape bags packed and in the trunk of her car.
Can Jon convince her Forbidden Lake is safe and to stay with him? Or will she run again, shattering her heart—and his—in the process?
