Sometimes the artwork on the cover catches my attention, or the title intrigues me, but the main thing for me is the blurb . Afterward, I read around 3-9 chapters before deciding if it's too confusing for my brain or if I should finish it.
That's a good way to go about it Blurbs really do make a difference when reading! I find I am always compelled to read them first XD Haha, don't want a book to be confusing! XD
