Hey Fmanie,
Learn photoreading, use it on everything, and activate all the novels you can. Use skittering and super reading and dipping, and also rhythmic perusal.
Now, it can work with novels right away, it IS a natural process, as Pete has said, correct?
The point of using non-fiction is not because it's the ONLY thing you can use, it's just easier to build confidence in beginners and to hone skills so that they may use it on everything.
If you photoread a novel, I would use skittering and rhythmic perusal mainly, to activate it.
So, photoread everything, activate all the novels you want to activate, then if you have time, activate the non fiction books you photoread too. After using the process on everything, you will easily be able to apply it to anything as well, novels included.
Try as hard as you can to not be frustrated.
