Oh! HI! *pounces* (Sorry, I read this book four years ago and have basically made it my mission in life to get everybody to read it.)

SO. "At Swim, Two Boys" by Jamie O'Neill. It's incredible. Buy it. Read it. :D

(It takes a bit to get into the language -and the prologue is way harder than the rest of the book- but it is so worth it, and it is so, so beautiful.)
