Jeanie and Amber Malkin - identical twin sisters - are new students at the 100-year-old Greenwich Private College, a boarding school in North Sydney, Australia that lies on the edge of vast, virgin bushlands. After settling in and meeting new friends, the girls learn an unsettling secret: time and time again over the past century, students have wandered off into the wilderness surrounding the school and vanished without a trace, never to return. They both begin to have strange dreams and are scared of the school. Jeanie and Amber begin to discover the mystery behind the disappearances and also the reason why the college's creepy vice-principal carries such a prejudice against identical twins.
The series only has three books and you could read the first two on Queenie Chan's website. I'll leave the link below, sadly you'll have to buy the third book I got mine for $7 online I could've gotten for less if I had Amazon prime XD but was too impatient to go to my friends house and order it there.
All that aside its a great read I enjoyed it, the ending could be pretty confusing though I had to reread it a good five times to get it, but still I could read it over and over again and not get tired of it. I hope you put it on your reading list and hope you enjoy it, your welcome if you do. Forgot to link lol http://www.queeniechan.com/manga/the_dreaming/1/ Oh and I heard it was going to be turned into a movie or series or something hope that comes true.
