Why hello there little boy/girl. What's wrong? Are you lost?
Heh, pardon me, I just had to say that. Welcome to the forum!
I've only encountered the Hmong in this book I read, quite good, actually. It was either Helen(a) Zia's Asian American Dreams or Frank Wu's Yellow, but they were both really good. I don't remember why the Hmong were mentioned (probably something about discrimination), but for some reason the name stuck. If you ever get a chance, be sure to look these books up!
Enjoy your stay!
