We have two words for you: Capaill uisce. These are the hardest two words to pronounce in the whole book, but once you get to Chapter 13, Sean and George Holly finally get hooked on phonics and spell it out for us: "Copple ooshka" (13.3). Once you have that down, you're golden—reading this book will be as easy as a leisurely ride on a beach. Just watch out for leftover body parts; those copple ooshka are mean.
