Death's Master

"Harry, I am Death," He drawled out slowly, "Of course it's allowed!" When Harry Potter see's Death, instead of Dumbledore he gets given a chance to undo history. Armed with his wand he stumbles fifty years into the past and lands straight into Charlus Potter and his friends. But when he meets a teenager called Tom Riddle, all is not as it seems. Dumbledore bashing. Tom/Harry.
