The Struggles of Trying to Read a New Genre

I have been reading Veronica Mars: The Thousand Dollar Tan Line for the past few weeks, and while I extremely enjoy this book, I'm finding it a little difficult to try to read a genre different from the one I'm used to. My favorite genre is sci-fi, especially  dystopian novels, like The Hunger Games or Divergent, but this book is a mystery, and it is structured in a very different way than what I'm used to. I have a problem with reading the last chapter of a book before I read the first, and I have been forcing myself not to find out who murdered and/or kidnapped college spring breaker, Hayley Dewalt, until I actually finish the book. As a result of this, I find myself trying to solve the mystery on my own by highlighting almost every sentence about someone that is close to Hayley and considering it "a clue", such as a description of her ex-boyfriend's hair and eye colors, or the fact that Hayley's sister wears black eyeliner like most of the sane women in the world who choose black or brown eyeliner over colors like blue or green, or the fact that her family is staying on the third floor of a hotel. It isn't the whole mystery and murder thing that throws me off, it's the fact that I am seeing the murder mystery in words on pages instead of watching it documented in an episode of 48 Hours. (I don't judge your interests, you don't judge mine.) But I have picked up something from all of the hours I have spent watching 48 Hours, other than learning that 95% of the time the spouse did it, and that is that the most obvious suspect is never the one who commits the crime, unless of course, the most obvious suspect is the spouse. So, seeing that I'm only 1/3 of the way through the book, I'm going to have to keep guessing and keep reading.
