Marcus Valerius Pulcher, a Roman noble raised on music rather than war, is sent to Germania’s raw frontier under the ambitious governor Varus. There he meets Ingomar, a Cherusci warrior, and finds something neither of them has words for, something a cithara, a hidden grove, and two empires’ worth of duty were never meant to allow.
But peace on this frontier is a fragile, borrowed thing. Warnings go unheeded. Confidence curdles into catastrophe. And as history’s most infamous ambush gathers in the forest ahead, Marcus and Ingomar must decide what love is actually worth paying for.
