Some years ago I discovered Wattpad, an app and a website to read free novels. All you have to do is sign in and then you are able to use. You can find books written by famous writers or by users, and when you like the prologue of one story you should add it to the library. So if you cannot read all the story in one moment, you can continue reading later.
