To Harry Potter, Fifth Year seemed like the same as any other. Classmates, homework, new dangers, Voldemort risen in the shadows… the usual, even with a Dementor attack kicking things off. But how long can he maintain the illusion that everything is under control? As hope for a normal life slips away through his fingers, will Harry bear the weight of it all... or will it crush him?

What if instead of dying, the Killing Curse sends Harry two years into the past into the Department of Mysteries? Will Harry be able to save those who died for him and destroy all the Horcruxes without Voldemort knowing or will he end up dead himself?
