This book has it all. Complex Japanese feudal politics. Sword fights. Multilingual international intrigue. Lots of surprising facts about Japanese society. An attack by the dead.
It bothered me that while the book is "history" so much of it is clearly invented. There's no way that our authors knew exactly what Yasuke thought or how he acted on a moment by moment basis. That made it hard to determined what was fact and what was invention. Despite that, I just enjoyed the book so much that it made up for itself. It even mentioned the suburbs of Philly, always a plus.
