Mine isn't too great either! I have trouble with a lot of Irish's grammatical quirks (especially the case system, because it's absent or at least invisible in English).
Half of the challenge of reading in Irish is getting your hands on the books! There are a few Irish publishers, but books in Gaeilge aren't found in ordinary bookstores. I'm lucky to have a friend in Connemara with a massive collection of books. Gafa is the only Irish book I actually own; I found it in the "Foreign Languages" section of a second-hand bookstore, and when I told the aforementioned friend's mother, she was actually upset that it was found there.
