I received a copy of this book for free through a Goodreads First Reads Giveaway.

An interesting examination of someone not many may know about. The book is very well researched with many notes which were useful throughout. It's not necessary to read the notes, though, to get the complete picture. While Lockley does drift into 'historical fiction' a little (describing how Yasuke 'feels' at certain points) it's not done excessively, nor does it really distract.

I really didn't know much about feudal Japan, so the history within was interesting and new to me, which I appreciated. It's not only an account of Yasuke, but also of the time in which he lived. Warlords, battles, and plenty of historical content throughout. Pick it up if you are interested in specific eras of Japanese history, or just history in general.
