The Marauders and the Lost Heroine (Harry Potter and Percy Jackson Gods)

Was I, Liv Silver, supposed to jump off my bed screaming little muffled cries behind my pillow like an annoying princess-like girl when I received my Hogwarts letter?
Huh, no. Merlin, no.
Was I supposed not to punch someone (or specifically the first person to bump me in the row 9 3/4) that was idiot enough not to bump me while I was pissed off because an annoying thing called a 'dad'?
Mmh. Nah.

But if I knew where this whole situation was leading I would've certainly locked myself up in a tiny room that day... Even though I'm claustrophobic...

Alert: this is my kind of first book so don't judge too harshly, but if you don't like, don't read!
Also, all the characters and the story belong to J.K Rowling but the principal character, Liv, and the plot is mine.
And... This book contains a lot of swearing, read at your own risk.
