Play audiobooks with chapter selection on iOS I have a number of DRM free Audio Books which I listen to while walking the dog, when I put them on my iPod Classic I can scroll through the chapters and pick which one I want to listen to.

On my iPhone the file appears as a single 33 hour audio file. I'm lead to believe that this is something that has arisen since iOS7 was released, as there are a lot of threads complaining about it after upgrading.

Is there a way/third party app that will allow me to scroll through chapters, or at least carry on where I left off if I decide that I'm going to listen to music between dog walking sessions?
Yes, you can use either Audiomark or Bookmobile.
