Harry Potter; Save me please (Mooney, padfoot and prongslet)

It had been almost three years. Three years of being tortured every single day by dementors, three years since that agonising walk into his best friends house knowing exactly what he was going to find and yet still praying he wouldn't, three years since he held his best friend in his arms and prayed to any forces out there to just please bring him back, that he would do anything, anything at all. It had been almost three years since he had been abandoned by everyone he held dear. The only thought that kept sirius even slightly sane was that of his godson and his trusting, smiling face. So what happens when sirius finally gets his trial? When sirius gets freed only to find out his godson had been abandoned by the magical world and sent to live at Lily's sisters to 'protect him'. What happens when he finds out that they have been abusing baby Harry? Abusing him in disturbing ways. Will he still have a friendship with dumbledore? With anyone?
