The Amazon reviews are precious:

Yakuza Dynasty is my favorite of the Code Name: Dodger series for many reasons, but especially because it digs into Justin Reed's past in such unexpected ways that I almost finished the book without fingernails (from all the nail biting). The author has an incredible talent for descriptive writing (and writing, in general), in a way that it appealed to all of my senses as I read this novel from beginning to end. It got me laughing hysterically, crying like a baby, and all that's in between.

It turns out the author is an airline pilot. I looked him up, and he seems like a pretty cool guy.
