The moment I laid eyes on Zack Lawson, I knew he was trouble. I was ready to dive in and go blind, but after an encounter with one of his conquests, I decided being friends was the best route. For three years, Zack has been my rock, but lately, he’s become a possessive jerk at the mere thought of me being interested in another man.
Finally, after a terrifying moment that wrenched us from the Mardi Gras ball, he kissed me, and my world changed. Now, I can’t stop thinking about him and all the things I want to do with him between the sheets. The problem is, Zack has no intention of having a serious relationship, and I can’t let myself fall for him and risk damaging our friendship. That’s why I’ve been avoiding him for the past few months while he has been trying to change our relationship from friends to lovers.
 
But now, as I prepare to take my students on a trip to Costa Rica, guess who volunteers to join us for seven days? Yup, you guessed it—Zack Lawson. How am I supposed to stay away from him when I’ll be trapped with him and eighteen students in a beautiful paradise?
 
Can I keep my heart intact, or will Zack break down my walls and claim it for his own?
