Harry Potter kneeled on the muddy ground at the base of his parents' graves in Godric's Hollow. It was two months after his sixth year at Hogwarts School of Witchcraft and Wizardry ended. Two months after he had seen Albus Dumbledore murdered at the hands of Severus Snape. He and his best friends, Ron Weasley and Hermione Granger had gone to spend the first half of their summer at the Dursleys, Harry's muggle relatives, to renew the blood ward just as Dumbledore had wanted Harry to. It was the last order he would ever obey from the revered Headmaster. Harry felt as if he had lost a precious member of his family, and it made him want to know more about his mum and dad, Lily and James Potter. After Harry, Ron and Hermione had left the Dursleys a few days ago, Harry told his best friends that there was something that he needed to do, and that he needed to do it alone. He encouraged his friends to research more about Voldemort's Horcruxes so while he was gone and told them that when he returned, they'd leave to track the rest of them down.
Harry had arrived in Godric's Hollow to see the rubble of what had been his family's home when he was a baby. He was filled with such a sense of loss he had never known as he looked upon the remains of the house. He wandered around until he found a small cemetery and found his mum and dad's graves. Harry fell to his knees at the base of the graves. He mourned their loss as he had never allowed himself to do before. He talked to their spirits and told them of everything that had happened since they died, detailing the Dursleys neglect and abuse, going over every thing he had been faced with since starting at Hogwarts. He told them about Dumbledore's death. And he cried until he had no more tears left to cry.
He was filled with a pain that wrenched his heart and took his breath away as he spoke to his parents' memories. When he had finished telling them about his life, he leaned forward and kissed the cold stone graves, tracing the letters of the inscriptions. He felt a sense of peace that he had never felt before, a sense that his parents were with him. Harry stood, the dried tracks of his tears staining his face, his eyes puffy and red, and he smiled. He rested his hand for a moment on each grave and then turned and walked away, knowing he would never again walk alone.
When Harry arrived at the Burrow, the Weasley's home, there was a happy sparkle in his eyes that his friends had not seen since their third year. He was more cheerful than he had been in years, and, most importantly, he was filled with such a sense of determination it made the air around him crackle with power. He and his friends attended the wedding of Ron's oldest brother Bill to Fleur Delacour and, mere minutes after the final party for the newlyweds, he turned to Ron and Hermione.
"Let's go, guys. We've got Horcruxes to destroy. Voldemort won't know what's hit him when I finish with him."
And his friends knew that Harry was ready. Voldemort wouldn't stand a chance, they thought, as they saw the determined glint in Harry's eyes. There was a battle coming, and Harry was more than ready to see it to its end.
