As a Guardian Angel, it's Arthur's job to protect humans from harm. But when he's struck by lightning and crashes in an alleyway in NYC, it takes has-been hero Alfred Jones to get him back on his wings. While Arthur heals from his injuries, he discovers that his hero perhaps means more to him than other humans, and learns that Alfred has his own wounds to overcome.

Here in the walled-off pleasure district of Edo, the last thing Commander Arthur Kirkland of the Royal Navy had expected to find was a golden-haired American in Japanese robes, an elite entertainer with a strange and supernatural clientele. Even more surprising is the powerful connection Arthur feels to this man whom he doesn't even know.
