In the dying days of the Second World War the Red Army swarms into Berlin to break the last defenses of the Reich, throwing themselves into the brutal struggle to rid the world of the Swastika's blight once and for all-and to establish Stalin's vision of a new world order.

Into this slaughterhouse the U.S.'s Office of Strategic Services drops top agent Ardell Murto on an audacious mission: to assassinate Hitler and bring the war to its final, all-but-inevitable end before Stalin can plant his jack-booted minions on any more of Europe.

But a flawless insertion is marred immediately by an unexpected development-Ardell's on-again-off-again colleague, the alluring and deadly Galya Porishnikov of the Soviet Secret Police, is there ahead of him. And to make matters even worse...

His estranged father, Waffen-SS Captain Rolf von Heydn, is among the defenders.

Ardell is a control freak. Galya has an unhealthy passion for inflicting death and a desire to leave behind her Soviet masters. And Rolf... Rolf is a unique specimen, and in another time and place might have been labeled 'neurodivergent'.

Now Ardell has to get out.

And Family Closest Of All is a tale of mistakes, regrets, repentance, and the price of forgiveness... the strains that can tear us apart, and-maybe-the acts that can bring us together again.
