Post 5th year, Voldemort is killed instead of Sirius. Ron and Lavender dated in 5th year and are still dating. If you don't like Ron/Lavender pairing, then just don't read this fanfiction.
Prologue:
Bellatrix was laughing as she duelled Sirius and they danced around, mocking each other. Harry panted as he struggled away from Malfoy, finally mustering up the strength and blasting him away and pulled the shattered glass from the prophecy out of his leg. Suddenly a jet of green light flashed mere inches away from Sirius's face, causing his hair to flutter slightly. Harry gave a horrified cry and turned, yelling Remus's name who spins around, sees the danger, and goes to help his friend.
Harry watches, his heart pounding against his chest. Sirius would be safe, he had to be. Suddenly, his scar felt like it was on fire and he doubled in pain. Cold fingers wrapped around his arms from behind him and his voice was silenced before he could scream for help. He glanced to his side as he was lifted up, all the Order members occupied in duels, Neville have been body-binded and his eyes were wide as he watched the death eater who had got Harry in terror.
Harry then felt ropes twist around him, and the cold fingers let go, and he plummeted to the floor, giving a silent cry and landed hard on his side. He groaned as pain spiked through him, only to look up into red, glowing eyes, see a slit, flat nose, stretched nostrils and a white, chalk coloured face. Voldemort.
"Well Harry, it seems like you're forsaken, not even your godfather cares about you enough to try and save you, he would rather kill his cousin instead. So, let's have a little fun then, shall we?" he pointed his wand at Harry's scar and says softly "Crucio."
Fiery pain exploded through Harry and he collapsed, screaming silently. His nerves felt like they were on fire and he curled up in pain, thrashing around. A salty taste rose in his mouth and he felt a liquid fill it. He coughed it out, red blood spilling out. Everything was blurry and swirled and he barely felt tears falling from his eyes as he choked on his own blood. The more he tried to breath the more extreme the stabbing pain and he held his breath, it becoming more shallow by the second.
Neville started to roll, though completely still on his back he rocked back and forth until he fell down the steps. Sirius and Remus, having blasted Bellatrix back, looked up and saw Neville. Remus quickly freed him but both froze at Neville's words. "Voldemort! He's got Harry!"
How hadn't he noticed, Sirius berated himself. He bolted towards Harry, Remus at his side. Remus, using his extra werewolf speed, reached him first. Both began to duel with Voldemort. Sirius was desperate to get to his godson but had no way of being able to without getting him hurt. It was however killing him to leave his godson on the floor like that, so severely injured. Suddenly Neville cried "Expelliarmous!" and Voldemort's wand flew out of his hand and he looked at Neville in shock.
Harry saw his wand lying only a foot away and crawled towards it, shaking so badly but he couldn't let Voldemort kill Sirius and Remus, he couldn't! Raising his wand, his hand trembling badly, Harry muttered a curse and blasted him to the dais. Voldemort gave a scream as he was flung up in the air and slammed back with full force into the veil. He twisted, screaming curses never even heard of by most in the room as his body fell through, yet not falling through the other side. Sirius bolted to his godson, who had slumped to the floor, drenched in blood. He checked Harry's pulse, having pulled him onto his lap. There was nothing.
