Chasing Her by Kat T. Masen

I hear his words echo in my head.
The voice telling me to leave her alone.
The threat to end my life should I dare go near her.

Julian Baker had it all. Stunning good looks, wealth, intelligence, and the girl. To everyone around him, he was Mr. Perfect.
Fate was never on his side, and much like a domino effect, his life starts to spiral out of control. Behind the mask lies a broken man, haunted by his tragic past. In a bid to forget, he finds himself desperately trying to hold on to someone who is equally unattainable, Charlotte Edwards.
In a last ditch effort to save himself, Julian reaches out for help, but the universe has other plans when someone completely unexpected walks into his life, and an unlikely friendship is formed.

His enemy’s sister—Adriana Evans.
