FBReader is fast and highly customizable. You can use external TrueType/OpenType fonts and custom backgrounds, the screen brightness can be adjusted while reading (slide finger up/down along the left screen edge), and different day/night color schemes can be selected.

Alternatively, you can download books manually and save them on your device in /sdcard/Books.
