Free Irish books + Audio reading
Here is a link to a website that has 2 free ebooks in Irish (PDF format), along with an audio reading of the chapters.
They have organized the page so that you can open a chapter on your screen and play the audio file at the same time, as well as play a video discussing the chapter after you have read it.
I believe it may not be the complete books (might have to pay for that) but it's still very good listening/reading practice.
Even if I don't understand much, it's a different voice than the duolingo lady, and I get to practice recognizing a written word and its pronunciation amidst longer sentences.
