The first ever novel...................... ....

This is the very first novel I've finished. I encountered here the word "aye", and I'm not familiar with this word so i searched it in my dictionary but I didn't find it. So as I proceed in reading, this word serves as a hindrance to make me understand the sentences including this word. But at the middle of the story, I just whisper to myself "ay.. yun lang pala yun.. hahaha"  The word "aye" means YES!!! hahaha.. (now you know) =D
