Well that's basically pleasure-reading if it's fictional. I wouldn't photoread fiction as I stand now, but if you were to photoread it, then I wouldn't think it to be any different, except that there may be less pleasure, and it may be easier than photoreading non-fiction which have a lot of facts to absorb.
Instead of being captured by a fictional book, when photoreading, you will be skimming the surface, and probably won't be captured. Your mind will give you cues and draw you towards things, but photoreading(without lucid dreaming) usually won't bring you the same pleasure as consciously reading the book.
