Royal by Dale Mayer

A prisoner of the Kremlin and of a failed exchange several years ago, Royal is losing hope of ever being free again—particularly when the firing squad date is already set for his execution. He has exhausted all avenues of escape. Now it seems to be the end of the line …
Janna has been through way-too-much pain and anguish recently, and yet somehow she can’t walk away from helping Royal, even though he’d walked away from her a long time ago. Maybe because she has nothing left to care about, this would be her last gift to give—if someone can just get to Royal in time.

Time is against them. Conditions are against them. Enemies are against them. Can they fight the odds, and, in the process, save themselves?
