We probably all do and just don't admit it

Who else here does that? So on to Angels and Demons by Delaine Christine:
One fateful night, Veta Rohann survives a nasty car crash that kills her family. As a result, the car crash brings up dark parts of her past and leaves Veta feeling like God is telling her to start over. With nothing but her U-Haul of meager possessions, she goes to Kalispell, Montana. Things don’t quite as planned, however, when she arrives. Her U-Haul gets stolen and she almost dies in her rental house’s hot tub. She starts to have feelings for Drinian, but is afraid she’ll get hurt. As God’s angels try and stop the demons from attacking Veta, the reader soon learns that Veta and Drinian are destined to fulfill a prophecy that could save the world or destroy it. With love and the world on the line, will Veta and Drinian fulfill their destinies? Will their dark pasts get in the way of their future?
I'd say this book is more of a supernatural fiction book than horror.
Supernatural elements I noticed that tend to be universal throughout the genre include otherworldly beings or forces and the ability for the main character to see and/or interact with them. I also noticed that laws of physics/science tend to go out the window with relation to them. They're usually something you see from old legends and myths.
This particular book contained all of those elements and took the form of the angels and demons you see as you read the book. Most of the main character by the end of the book either have supernatural powers such as reading minds and/or can see the angels and demons. come in to account when you learn about the family's past and how Drinian is part of a triplet set where at least one is evil according to their family's traditions.
I liked the cliffhanger chapters and ending of this book. It left me reeling at the end and ended totally different than I expected. I've noticed this also tends to be a characteristic of horror/supernatural fiction.
At first, I didn't like trying to keep straight Veta's cat and the main character guy being called, Drinian, but this later played into the story's mystery. I think mystery and confusion also tends to be a natural characteristic of the supernatural and horror genres.
What do you think? Do you think confusion on the part of the reader is a natural part of the book or are there some books you've read that this isn't the case?
