Dollhouse by Anya Allyn

For fifteen year old Cassie Claiborne, there's only one good thing about moving from steamy Miami to the wild inland forests of Australia--the even wilder Ethan McAllister. But Ethan already has a girlfriend--Aisha Damaj--the girl with a hundred different moods a minute.
When Aisha goes missing on a hiking trip in the local mountains--presumed dead--the whole town points a finger at Ethan. Cassie defends Ethan fiercely. She's just about the only friend he has left.
Is Cassie letting her feelings for Ethan cloud her judgment? Or does something dark lurk out there in the forests? From Goodreads

This was quite scary and didn't give too much away along the way. The worst part of it is that I just didn't realise that this was number one in a series, I totally missed the part where it says (Dollhouse #1) right after the title. I have to buy the next book now as it will be perfect for a Halloween read.
