Own Goal by Lyssa Lemire

I promised my best friend I’d look out for his little sister. I promised I’d protect her. Instead—I fell in love with her.
Have you ever had a secret so explosive, you hid it even from yourself?
For years, I’ve lied to myself about my true feelings for Brooke. The fact that she’s my life-long best friend’s sister makes her strictly off-limits. When she comes to Ridley University—where I’m a hockey legend—I promise her brother I’ll look out for her. And the lies start.
I lie to myself about why I chase off any guys who try to hit on her at parties.
I lie to myself about the sparks that crackle in the air between us.
I lie to myself about why my heart pounds when I hear her laugh.
I lie to myself about the desire that burns in my chest every time our bodies meet in hugs that are supposed to be “friendly.”
When I find out she’s been lying, too, we tell ourselves the biggest lie of all. That we can indulge our passions in secret for a limited time. That we can satisfy the lust that’s built up for years, and then go back to normal.
But one taste is enough to turn me into an addict. And this is one addiction I don’t want to quit. No matter what it costs me.
