Audible/Kindle immersion reading or Read&Listen - Anyone gotten this to work?

My main method for picking up Italian has been listening to audiobooks in Italian and reading novels (which is a lot more work). I'd really like to try to do the read&listen approach. But I haven't been able to find any novels where I can read in Kindle App and listen to the audio using Amazon's fancy immersion reading system (which sort of tracks and outlines the text as it reads aloud from your audible file). I bought one or two books in both formats but the feature is maybe only available in English? Anyone else tried to get this working?

Edit: Here's a link to Amazon/Audible's page on the feature.
