Jutsu gone wrong

After the death of her daughter Sarada in the fifth great shinobi war, Sakura drifts away from Sasuke and she learns to hate the man she once loved. Becoming obsessed and deranged with the search of ways to bring her child back to life, she delves deeper into her hatred, it spreading to the village that sent her baby to war. Once again attempting to revive her daughter, Sakura is transported back to her body the day of the genin exams. Instead of trying to return to her time, she opts to remain and change the future, to give herself another chance. So what if that means joining some rogue nin and leaving the village? She hates them anyways. And what's with this odd new ability? And why the hell does Itachi keep smiling at her?
