Gabriel McKnight, a decorated former U.S. Navy SEAL and bestselling author, sees his perfect life come unraveled when he's named the prime suspect in a murder case after his twin brother vanishes without a trace. Now on the run from the law, Gabriel embarks on a desperate worldwide quest to clear his name and uncover his brother's fate.

His only ally is Noor Rahman, the scion of a once-powerful Iranian dynasty whose past intertwines with a mysterious book of Rumi's poems left behind by her deceased parents. Together, Gabriel and Noor decipher cryptic passages suggesting a link between the historic murders of Noor's family and his brother's disappearance. From the back alleys of Washington, D.C., to the bustling streets of Paris, and the vibrant vistas of Tehran, they navigate a labyrinth of danger and deception leading them inexorably to Rumi's mystical resting place in Turkey.

But discovery comes with a perilous cost. With every revelation, Gabriel and Noor inch that much closer to unlocking the sinister truth behind their parallel destinies. Can they outwit their unseen foes and decode the final mysteries before they themselves become the final casualties in this deadly game?
