The Dreaming by Queenie Chan (amazon)

Twin sisters Amber and Jeanie are sent to an isolated boarding school deep in the Australian bushlands. Their aunt is the headmistress of the school, but she leaves for a trip after warning the girls not to reveal that they are twins to the vice principal. Rumors of missing past students circulate among the girls, and the twins begin having unsettling dreams.

I haven’t read tons of Tokyopop’s English language manga, but The Dreaming seems to be above average in quality compared to some of the other titles I’ve read. Queenie Chan’s fills the book with a sense of foreboding, using slighty off-kilter camera angles to make the boarding school seem extra creepy. I also like the Australian setting.
