Double or Nothing by Lyla Grace

Double or nothing: A bet resulting in the gambler winning two times as much or losing it all.
Five years. That’s how long it’s been since Kat Keller last laid eyes on Sutton Cole.
When he boarded that plane to New York, he took her heart with him and left her broken and alone.
When Kat finds out her newest client is none other than her ex, Sutton, she does everything in her power to remain professional and keep her distance.
Forced to be at his beck and call, Sutton doesn’t make things easy on her. The closer they get, the harder it is to resist him.

Can she forgive the man that tore her apart? Or is it her turn to walk away?
When Sutton Cole left Vegas five years ago, he destroyed the best thing that ever happened to him – Kat Keller.
With nothing left for him there, Sutton swore he would never come back.
When his record label signs him up for a concert that he can’t get out of, Sutton has no choice but to head back to Vegas. And straight back into Kat Keller’s life.
One week. One show. Then he’s out of there.
All it takes is one look into Kat’s eyes to make him reconsider.
Still haunted by his past, Sutton knows that staying in Vegas is the ultimate gamble. Still, there’s no doubt in his mind that Kat is worth it.
This time, it’s double or nothing.
