Now a fragment of encrypted signal surfaces at a Vienna listening post, carrying the exact cadence of a cipher only the two of them ever shared. Only two people ever knew it. One of them is dead.

To bring the Choir down, she must trust a man who let her grieve him for six years, learn which of her own colleagues can still be trusted, and confront a betrayal reaching into the highest levels of her own agency all while deciding how much of herself she is willing to sacrifice for a love the world insists never existed.
