Sofía Vargas escaped the man who owned her—but freedom comes at a cost.

When her powerful uncle hunts her down to reclaim what he believes is his, Sofía turns to the one man ruthless enough to protect her—Rafael De la Cruz, an elite operative of the Iron Covenant. Their solution is simple: a marriage of convenience that binds her to his world and puts her under his protection.

But nothing about Rafael is simple.

As danger closes in, lines blur between duty and desire, and Sofía must confront the past that nearly broke her. When the Covenant uncovers a traitor within their own ranks, the stakes escalate into a deadly game of deception and survival.

In a world built on power, loyalty, and blood, Sofía and Rafael will learn that some bonds aren't forged by choice…

They're Bound by Iron.
