The book is good but I noticed a few proofreading mistakes. Tang is not a Korean name. I am not sure an adult can have dual Chinese-American citizenship. Mah-Jongg is a Chinese game, not Korean. There were also a few punctuation errors. I am surprised this book was not proofread properly.

Mr. Thor:

I am an English teacher and would be happy to have a job proofreading your next novel.
