Keep Your Enemies Closer (джен)

Voldemort conquers wizarding Britain in Harry's sixth year, starting with a surprise attack on Hogwarts. Harry is allowed to live and his previous training with Snape merely... continues. When Voldemort saves his life, of all things, Hermione realizes he carries a Horcrux. Harry struggles to deal with friends and enemies alike, his strange influence over Dark Marks and Tom Riddle inside his head. He gets a chance at influence, but should he take it?
Gen, dystopia in which I attempt a gradual, realistic mentorship - between Harry and Voldemort (mostly) and between Harry and Snape. One reviewer says of KYEC: I just found this story a couple of days ago, and I'm thoroughly gripped by it. I could barely stop reading in between chapters, but had to, of course, since your tale is already so deliciously long. The plot is thrilling and well thought-out, and your characterisations are spot-on.
