His Best Friend's Sister - A Forbidden Office Romance #936275

She's my best friend's little sister. I'm supposed to protect her, not want her.
Emma Chen has always been off-limits. Alexander's brilliant lawyer friend who's too young, too innocent, and way too dangerous for a man like me. I've spent three years keeping my distance, ignoring the way she looks at me, pretending I don't notice how she blushes when I walk into a room.
But when anonymous threats start targeting Emma, Alexander asks me to be her bodyguard.
Now I'm living in her apartment. Watching her sleep. Fighting every instinct that tells me to claim what I've been craving for years.
Emma thinks I'm just doing my job. She has no idea I've been fantasizing about her since the day we met.
When the stalker escalates, when Emma's life is truly in danger, my protective instincts override everything else. Including my promise to Alexander to keep my hands off his precious Emma.
One night of passion changes everything between us. One kiss destroys three years of careful control. One touch makes her mine, even though loving her could cost me everything.
Alexander trusted me to protect Emma. He didn't know I was the one she needed protection from.
Now the biggest threat to Emma's safety is how much I need her.
She's forbidden fruit I was never supposed to taste. But now that I have her, I'll fight anyone who tries to take her away.
Even my best friend.
