There are zillions of books with vaguely medieval fantasy settings, but I love a fantasy world with rough edges and a very specific purpose. Half World is just such a place. It's one of three realms, which were once connected. People passed from the realm of the living to the realm of half-life to the realm of the spirit life and then back to living in a constant cycle.But somehow the realms were severed, so that living people were reincarnated without passing through the other worlds. Anyone stuck in Half World had to reenact their greatest traumas over and over again without every getting over them. And no one's heard from the Spirit Realm.
Enter a melancholy girl named Melanie Tamaki (Canadian-Chinese, I think?), whose mother is a vague, lifeless woman who lives like a fugitive. One day, Melanie comes home to find the phone lines cut and her mother missing. While she's wondering what to do, she gets an impossible phone call from a man with an icky sticky voice who commands her to go to a highway overpass and look for an emergency door. I bet you can guess what's on the other side.
