Hello Marita,
My brother Jacob told me to read your book! It was very cool. I enjoyed reading your book, it was worth it. I think you write beautifully! I have a few suggestion:
"Stephen ignored the comment. He grabbed the other chair and straddled it backwards."
I think it should be:
"Ignoring Chris's comment, Stephen grabbed a chair and straddled it backwards."

"The one-story brick building, with a shallow, sloping roof, was surrounded by farmland."
Instead of this:
"The one-story brick building, had a shallow, sloping roof, which surrounded the house by the farmland."

"He knew he shouldn’t provoke his cousin, as their fights usually ended in full on punch ups, but he didn’t care, sometimes even winding Stephen up on purpose to get a rise out of him."
Maybe:
"He knew he shouldn’t provoke his cousin, as their fights usually ended in full on punch ups, but he didn’t care, sometimes he even wound Stephen up just to get a rise out of him."

"But it was still worth it, plus he thought his tooth looked real cool until his mother took him to the dentist."
I think you need to do this:
"But it was still worth it, plus he thought his tooth looked really cool, until his mother took him to the dentist."
I think you need the comma.

Well done with your book. My fave character was Chris, no one could compare to him, he had it goin on, he was awesome. I loved it when he swore at Stephen in Italian. I also liked Reprebus, he was nasty, but good to read about. You made us feel like we were apart of the story. Each time you changed the narrater, I felt like I was the person, thinking and doing things. The title "The Blue Curse" was a very good choice, it is a very good title. I love how it's situated in New Zealand. New Zealand rocks! The comments I said were all that I could find. I re-read your book twice, so that's all I had noticed. It just got better each time. I also saw that it'll be the first in a series, I can't wait to read the rest. I saw the next one is going to be called "The Black Merge", I like the name, and would like to learn what a merge is. You made the overall ending very, very well, it was very chilling. For me it was a 5 OUT OF 5 FOR THE OVERALL RATING!

Well done, Marita. I'm looking forward to reading the rest!

Ciao, Marita.
I just looked at it, and yes it is much more clearer now. It is much better. Thumbs up. Gotta go.
Ciao, Leonardo.
