Stolen Dreams: Vegas Dreams #3, Callie's Story

"I'm leaving." 
A two-word declaration made by Callie's husband Josh as he stood in the doorway, duffle bag in hand, ready to make a quick escape. She didn't know why, or how long he'd been contemplating it, or even if he still loved her. The front door closed and she sagged to her knees, allowing the tears to rush forward as reality set in. He may not have loved her anymore, but she still loved him.

The Vegas Dreams series includes four novellas: 

Sweet Dreams (Rae's Story) 
Shattered Dreams (Sasha's Story)  
Stolen Dreams (Callie's Story) 
Summer Dreams (Kenna's Story)
