So when she gets an opportunity to run a psychology study to help her get into grad school, it should be no problem dealing with the prickly guy she suddenly finds herself paired with. The one she had a secret crush on last year. The one who refuses to let anyone close. The one she’s discovering by the day may have a softer side than he lets anyone else see… Tyler knows stress. He’s grappled with it for as long as he can remember. And just because he has to share credit with this girl on his new psychology study doesn’t mean he has to be friends with her.

Even if it means giving up the best thing that’s ever happened to him.
