Due to the lack of historical record's specifically referencing Yasuke, this book ends up being more about the people he served (Jesuit missionaries and Japanese feudal lords) than about the man himself.

Honestly, I would have preferred a book half this length that focused on what we actually know about Yasuke. The amount of detail about his employers goes beyond what's necessary to understand the historical context and feels like it's there simply to pad the word count. He's an interesting and unique historical figure, but this book makes him a side character in his own story.
