Introduction.
Nothing happens just because. Books do not appear out of nowhere, letters do not get lost without an explanation.
It is a pity that Andrea, Sophia and Nora don't know it. What are they supposed to do if they're just muggles in wizards' families? They don't know any spell, they don't wear robes, they don't believe in magic beyond tricks.
But, in the less expected moment, the less expected way, they see themselves involved in a world that had turn its back on them. They had never thought things could change so much one day to the next.
There are very few coincidences. If many happen to you, beware. Maybe, their story is just an amount of coincidences. Or maybe not.
First part of the tetralogy of "The Silver Trio".
DISCLAIMER: Even if the world and most of the characters are not my own, the rest of characters and the story are fully my own invention, and this is not part of the canon of J.K. Rowling, as is not meant to be. English is not my first language, so I apologize in advance for any mistake I could make. If you find one, I would be happy to correct it, so please report it to me. Thanks a lot :)
