It will probably come in an app form, but with it being LG software you would have to do a bit of research as to what file extension the phone can read, if its ereader.app or ereader.lgapp for example. Once you find the right one install it by putting it onto the SD card, or plug it in and it should work

If not, join a forum for the phone and ask on there, I guarantee theres one for it!
