Harry is two years older than canon with a bit of darker side on him.He is not the boy-who-lived Neville was marked. If you are looking for a Story with good grammer and structure i am sorry its not good though i think i have a decent plot.

Another what if story but something never done before Harrys parent are alive but no bashing. Harry would be dark and go to slytherin straight away. Not a bonding story. Harry is two year older than canon.His sister has same age as does canon harry. Will be in harrys and his sister pov. Pairings not decided for harry will either be carrow or greengrass. Oc sister/neville
