Why I won't be finishing a Book

If you check my goodreads and see that I finished the Zombie Survival Guide its not entirely true. I decided that as much as I hate to not to finish a book this one just wasn't going to be one I'd finish.

I tried hard to get through this book but it just wasn't happening. It's odd that a book about zombies bore me but it did. I think because i know it's a fiction book pretending to be nonfiction and making people think its the only book to be prepared for an emergency. As far as we know zombies aren't real and reading this book thinking if there was a zombie attack this is all they need. 

Anyone else read a book and then decide to stop because its just not worth your time.
