Holdout by Jaqueline Snowe

Jonah Daniels has enough to do during hockey season without spending time interviewing a roommate to help share expenses. So when some dude answers J.D.’s ad and agrees to his terms, he puts a key under the mat and leaves for practice.
What he doesn’t expect is that his new roommate is not a dude at all, but an overtalkative, energetic hottie. What’s worse? She’s the younger sister of his friend on the team, and she’s sworn him to secrecy.

Ryann Reiner needs a place to live, stat. After an incident at the dorms that almost tanked her scholarship, Ryann wants a boring roommate who’ll leave her alone. J.D. almost fits the bill. He lives and breathes hockey, just like her brother, and he wouldn’t know a joke unless it checked him against the boards.
He’s also gorgeous. And broody. And he looks fine on laundry day, in too little clothing. Soon, late night study sessions turn into dangerous flirting. And then a kiss turns into more. But they’re determined to keep things in the feelings-free zone.

Until lines blur and tensions rise when Ryann’s brother learns the truth. And both their hearts are skating on thin ice…
