Battlefield by Gwendolyn Casey

As a member of the Aces MC, nothing in the world is forbidden to Jordan Mitchell, and he is not in the habit of denying himself the things he wants. But when he meets his younger brother’s girlfriend, he finally knows the torture of wanting something he can’t have.
Cecelia Taylor knows Jordan would be a mistake since the first time she meets him. Not only is he a filthy biker but also an arrogant jerk who can never seem to keep his hands to himself. And yet, she can’t seem to resist those hands … or his bed.

Their relationship is a battle from the very beginning, with casualties on both sides. But when Jordan’s mysterious past comes calling, their love is put to the test, and they both have to decide if what they have is worth a real fight.
