Un'inattesa epidemia ha decretato la quasi completa estinzione del genere umano e la popolazione si è ridotta alla fascia d'età inferiore ai diciotto anni, fatta eccezione per un esiguo numero di individui adulti incomprensibilmente resistenti al virus. Leah avrebbe desiderato una grande festa, ma una sorpresa che le cambierà la vita la sconvolge proprio il giorno del suo diciottesimo compleanno; di certo non è il regalo che si aspettava...

The Marauders are starting their fifth year at Hogwarts; Remus is starting with a massive scar across his face - a byproduct of the increasing severity of his furry little problem, which is a definite cause for concern despite his insistence that it it's fine. Sirius is starting with the memories of a certain morning at 12 Grimmauld Place in August: memories that he might not ever forget, yet is desperate to cloak underneath the facade that every is fine at home and that he and his parents just sometimes encounter minor disagreements. James is starting his fifth year, yes, but more importantly, he is starting phase five of his plan to woo Lily Evans: somehow his friends seem doubtful that he might succeed, but James, being James, is in no lack of confidence. And Peter, well, Peter is starting to wonder just why he puts up with these people, and if he should really be feeling sorry for Lily Evans, and maybe if he should have asked to have been sorted into Hufflepuff.
