Exemplum memoriam miseris, viginti annis

Harry discovers a spell hidden deep in the Longbottom library. He copied and saved it until the September after he turns 30. The spell copies and sends back his memories to 10 year old Harry that now begins a divergent universe. Will see Dumbledore bashing and some minor selective Weasley bashing. Rating M for future chapters. I plan to complete all 7 years year before Hogwarts.
