Getting the Grinder by Brenda Rothert

Leo Abbott is screwed. His new teammate won’t stop trying to set him up with his twin sister—who unfortunately inherited the family unibrow. Desperate to avoid the world’s most awkward dinner date, Leo lies about having a girlfriend. Too bad the name he blurts out in a panic is a woman who absolutely despises him.
Mara Torres has zero interest in doing Leo any favors, especially after he proved what a Neanderthal he is. But the chance to make the cocky hockey player squirm? That she can get behind.
Their fake relationship starts as pure revenge, but somewhere between heated arguments and sizzling tension, the line between hate and want gets dangerously blurred. Now they’re facing their biggest challenge yet—what happens when enemies become lovers?
