The Marauders are back for their sixth year at Hogwarts but all is not well this year. Still up for their moonlight stolls with their favourite werewolf the Marauders must deal with their NEWTs and a new foe that has it in for them.

Regulus feels invisible withing Hogwarts walls, and he doesn't like it. Sirius overshadows him and Reg hates it. So Sirius concocts a plan to get his brother noticed, showing Reg that there is at least one person in Hogwarts who loves him no matter what.

Sirius and Regulus Black are two brothers who people do not assume get along. However, behind closed doors things are different, and when Regulus is forced into a destiny he did not choose Sirius goes to the extreme to help him. Not Sirius/Regulus.
