Unknown - Grace Sufficient, #1

He knew there was a cost. He just didn't know how great it'd be. Gabriel Kelly returned to Russia for one reason-to bury his parents. After ten years in the United States, he hadn't expected to return to his childhood home in the face of tragedy. However, after short days in Moscow, he begins to consider if the same call that cost his parents' lives is now upon him. Sofia Rykova's dreams finally came true when she became a principal soloist with the Bolshoi Ballet.
One night, though, an old crush walks back into her life, making her wonder if there is more to life than ballet. Gabe Kelly is just as she remembered, just as she longed for-yet religion stands between them. Unknown to Gabe and Sofia, danger lurks closer than either would have guessed. The deaths of Gabe's parents grow more suspicious by the day, and Gabe and Sofia are drawn into the midst of a plot neither can escape.
Will obedience to God's call-in spite of their fears and desires-result in a price too steep to bear?
