Meh. I just don't like the main characters - Cal and Daniel. They're childish, immature, self-centered and completely unsympathetic. They find their roommate dead, in their bed, between them, naked. They have no idea what happened. Do they mourn? Nope. They run - worried about their own skins. I do understand that, but I didn't even realize she was their ROOMMATE until later - when the police showed up there and found pictures/mentioned it. Seriously?
Then they break into some house to apparently trying to get off the island and back to the US, but then they decide to have sex on the floor (where Daniel gets his choking fantasy on). Maybe it was an affirmation of life, I don't know. By this time I just didn't care. I read the entire sex scene with a look of disbelief on my face.
The other two, apparent, main characters - Nico and Thena - just bore me.
I give up. This might just be me. I think I'm going to switch to something I know will make me happy.
