   Summary

   In the wake of Dumbledore’s fall, a hidden secret in the Room of Requirement thrusts Harry into a Hogwarts of 1977—a world both familiar and strange. Sorted into Slytherin and tangled in alliances he never sought, Harry must navigate the shadows of rivalries and loyalties anew.

   Amid the quiet tension of the Marauders' era, a wary bond with Regulus Black may become his greatest risk—and a tether to a fate he never expected to claim.
