The summary confused me a bit. She's straneded on an island - no one can sail to - yet, she's being sent to a boarding school? Hmm. Anyways, onward. I'd really, really like to see what happens to super social Samantha. :)
I liked this. I liked it alot. It was really kind of interesting, you know? All this speech. I think the only thing I could recommend is that you balance everything out. You know, add in more detail? When it's just straight speech, the reader doesn't get a feel for the character - "talk is cheap" - and it's hard to tell what exactly is going on in a story - especially like this, when it seems to be so jumpy.
Now, I only read the first chapter, but I'm sure this story gets better and better. You're an amazing writer, dearie. c: <3
