Audio book coming out in the fall

My book that's coming out this fall, Heart's Journey, is also going to be released as an audio book. I found this out after it had already gone to print and it was too late to change it. My unfortunate narrator is going to find himself faced with some Cree and Blackfoot words to tackle. I'm sure he'll do fine. I mean, what can go wrong with words like I'taamikskanaotonni and Sooyaisiihtsi?
