Rescue the Nightingale

At the onset of the war, a humanitarian aid worker suddenly goes missing in Ukraine. Connor, a former Navy SEAL and ex-CIA operative, had long left behind his life of violence, but to save her, he steps back into this shattered land. Alone, he crosses the volatile warzone, facing mercenaries at every turn, with the ever-shifting front lines threatening to swallow him whole. Even more daunting are the shadows of his past he thought he'd buried. Amidst the ruins of a devastated city, he must navigate the cracks between warring factions to find the missing woman, and in the hail of bullets, settle scores with his own history.
