No fuss simple reader that works for me.

Spent a short while experimenting with the settings, but now that I have it set up,its my reader of choice. Best features: Simple thumb flick up to move to next page; easily customizable layout - I prefer two columns on my iPad so I dont have to scan too far across the page with my eyes; keeps current page you are on with no fuss - simply go to recently opened menu to return; simple tap to bring up options menu (and also shows current pg you are on, although personally I would like to see the page number always shown while I read, like a paper book, but good enough); touch and hold a word you dont know to bring up a define option. I use that all the time. I recommend the reader. I have no affiliation with the developers.
