Magical Liaisons

AU. Lily is alive and Sirius and Remus are helping her raise Harry. Neville's parents are sane. Harry meets the OC and Hermione in muggle school and they grow up with Neville. (Eventually Neville /OC and Harry/Hermione) Bad summary I know. I'm not sure if the title fits so it might change. Alive!Lily, Free! Sirius. Sane!Longbottoms
