I don't know what fleurons are but I'd probably not like them either
Just gimme the story, no frills, no previews, no author bios or also by...
Maybe my dislike of extras comes from all those annoying unskippable things there used to be on rental dvds. I should be grateful that no one has invented unskippable epub front ends. Yet!
But I also like the story to end at 100 percent so I can use percent read as a reliable indicator,
