Ben Rider and Nikolas Mikkelsen learn that danger comes in all shapes and sizes and often in places you least expect it. Nikolas's dark past calls to him, inexorably dragging him back into its seductive embrace.
While he goes on an errand of mercy to Russia, Ben travels to Denmark to learn Nikolas's language. Convinced Russia's vastness will swallow Nikolas, Ben doesn't see the enemy much closer to home. Thinking he has lost Nikolas, Ben then makes a terrible decision that threatens to destroy everything they have together.
Focused on this very personal horror, bound by a new level of commitment, they have no idea that a greater threat is coming. And when it arrives, it changes everything—even the definition of commitment.
