Knockout by Jessica Prince

It wasn’t fair that the man I hated with a passion was so freaking gorgeous.

Things in Layla Fox’s life were going great. She had a fantastic job, amazing friends, and a killer apartment. There was just one tiny glitch in all that perfect. Her upstairs neighbor was the very definition of tall, dark, and handsome . . . and she hated the man with every cell in her body.
Jude Kingsley was the most arrogant jerk she’d ever met, making the fact that she was attracted to him more than a little inconvenient.
When the two of them are forced together by Jude’s meddling grandmother, the bitter rivalry between the two feuding neighbors suddenly turns into something very different. And a raw, intense chemistry like theirs is bound to explode if they aren’t careful.
