The Job by Cara Dee

With the help of their ball-busting daughter, some questionable morals, and an important job to get done, Casey and Boone will steal you away to the grit and glitz of Las Vegas in this fast-paced romance.
I’m not supposed to do this job without Boone.
We may not share genes, but it’s been us against the world since his mom took me in as a toddler. The rowdy O’Sullivan boys who raised all the hell that Vegas could handle. Not that all my memories are wild and make my heart race. After all, I realized I was in love with the bastard at some point, so there’s been plenty of pathetic yearning and jealousy too.
Even so, it’s been him and me. Brothers, partners in crime, and, for the past six years, co-parents to an amazing little girl. But that’s another story. Right now, I gotta focus on the job our cousin gave us, and I need Boone by my side.
The problem is we haven’t really been on speaking terms for four years now.
