the Marauders story- year one

James Potter, Peter Pettigrew, Remus Lupin and Sirius Black are all nervous and excited for their first year at Hogwarts School of Witchcraft and Wizardy. Nobody at all expects thoes four to become friends because there all so different, Sirius Black the sole heir to the black family, James Potter the sole heir to the Potter Family, Remus Lupin the mysterious person who everyone wants to know about but no one does and Peter Pettigrew, his the sole the heir to the little fortune od the Pettigrew's.
Each with their own reason to be, each one of them are harbouring secretes in which they shall never tell any one, or so they thought.
They find loyalty in each other from the very second that they shared the same train compartment, but the question remains will their loyalty between four 11 and 12 year old boys, or will they crack before the year has finished?
