Manacled Book by SenLinYu
Manacled Book is a “Harry Potter” fanfiction written by SenLinYu, set in an alternate universe where Voldemort wins the war, killing most of the resistance including Harry Potter, and forces Hermione Granger to become a captive surrogate for Draco Malfoy to repopulate the wizarding world, with the story heavily inspired by “The Handmaid’s Tale” where Hermione is held prisoner and subjected to psychological manipulation to extract hidden memories crucial to the regime; it explores themes of trauma, captivity, and forced reproduction.
Harry Potter is dead. In the aftermath of the war, in order to strengthen the might of the magical world, Voldemort enacts a repopulation effort. Hermione Granger has an Order secret, lost but hidden in her mind, so she is sent as an enslaved surrogate to the High Reeve until her mind can be cracked.
