AUDIOBOOKS
Note: Audio books should be downloaded using a computer over a Wifi connection as the files are well over 400mbs each. Once files are downloaded, use iTunes (if you're on an Android you'll have to figure it out yourself sorry ¯\_(シ)_/¯ ) to sync them into the Books app onto your iPhone or iPad. Using iTunes is the only way you can get audio books onto an iOS device at this moment in time. (Thanks Apple (◔_◔) )
