Harry Potter was destined to stop Voldemort from the moment he was born. This time, he was destined to befriend Tom before he ever became the Dark Lord. What changes does this spell out for the wizarding world? Read and find out. Harry goes to school with Voldemort! (Not the best summary, I know, but give it a chance)

Before Sirius is captured and sentenced to life in Azkaban he brings Harry to a group he can trust to protect and raise him. Trained to use magic from a young age, raised in an unconventional family, and above all taught to resist the manipulations of others, Harry steps into the wizarding world and changes everything.

Just a quick one-shot I think has an interesting idea in it. Dumbledore adopts Harry and Harry befriends the Weasley twins their first year. Might turn into an entire story later on.
