I listened to Long Black Curl with the Audiobooks app. Bookmarks, sound quality, playback options, and search features are fantastic. The only drawback is the app interface when actually trying to listen. Other apps open directly to a screen for book playback where this does not. You have to hit the "now playing" button or get lost in the odd places clicking on the actual book title will take you. Its not a big deal...having to hit one extra button...but it really seems to slow the process down quite a bit. Cure this and youd definitely have a 5 star experience.
