The Rosett Legacy

So, where do I begin? To say this is like one of those adventure books which are usually filled with magic, thrilling story-telling and a road full of self-discovery would be an understatement. If you think this book is some kind of fanfic-twilight bullshit story (no offence fanfic readers), then just stop reading. What were you thinking to begin with? Cause as I see it, this book has many strong kick-ass characters which the faint-hearted won't be able to deal with. No, I am not exaggerating. You need to stop underestimating the power of Thor.... oops, wrong universe.
Forget whatever I wrote back there. Back to the main point: two lines later, I will go all fairy-tale like and you just need to follow through. The main story should start after you tap "Chapter 1" (no shit Sherlock). Once upon a time, in a land far, far away there once lived a family of six (told you I would go all fairy-tale like). The family of six had many adventures, from the parents going to work 9 to 5; the children having their own adventures e.g. puberty and stress from deadly homework. These adventures were same for every child in the world (but we live in a world full of batshit self-centred fools - so the adventures are centered around them only).
However when Oliver, the youngest of the siblings, turns 18, many strange things occur and a prophecy no one wanted to face was unknowingly awoken again. Unknown to the Rosett sibling is the fact that this unwanted prophecy is about them. Demons are on their tails; Death and Lucifer are invited to the party. Ladies and gentlemen, I can officially say that all hell is about to break loose.
