West Berlin, 1961. The Wall is two months old, and everyone is keeping secrets.

Dan Carter arrived in the divided city wearing the face of a brash American journalist ? a cover hiding the intelligence officer beneath, and a deeper secret buried so far down he has almost convinced himself it isn't there. His assignment is simple and brutal: find the traitor feeding military secrets across the line before the betrayal costs more lives.

Then a single evening in a glittering embassy ballroom changes everything. On the other side of the Iron Curtain, Alexei Volkov has spent his life perfecting a mask of his own, surviving in a system where a wrong expression can end you. When the two men collide, each recognizes something in the other that neither can afford to feel.

As the mole hunt tightens and internal security begins to circle, Dan learns that the most dangerous thing he carries isn't the secrets in his radio or the gun in his waistband ? it's the truth about who he is, and who he's beginning to fall for. In a city built on division, loving the wrong man could mean exposure, ruin, or death.

Some walls are built of concrete. Others are built of fear.

Checkpoint Charade is the first book in Iron Curtain Hearts, a slow-burn MM Cold War spy thriller series of forbidden love and impossible loyalties. A complete story with a deeply satisfying ? and unforgettable ? emotional payoff.
