Josie and Jack

This whole book had a dark, creepy feel to it. Josie and Jack are teenaged brother and sister, living in western Pennsylvania with their father, a college professor, frequently absent from their lives and he isn't really all there. They are home schooled with not much contact with the outside world but Jack has more contact than Josie. They eventually both run away and...well, I don't want to spoil the story of what happens next.

The book has a very V.C. Andrews feel to it, if you know what I mean. The story keeps moving and you keep wondering what's going to happen next and the climax is shocking.
