Luke of Luke Reviews checks out The Lord of the Sands of Time and writes, in part:

...Ogawa picks interesting times to jump back to, from the dawn of mankind to World War II. Orville and Miyo become very human characters that are easy to relate to, and when they are in danger’s way, suspense fills you over their well-being.

It does, you know.

Also, over at SF Signal, JP Frantz also raves, saying:

After seeing humanity effectively wiped out in stream after stream, O is full of despair, but continues to try to save mankind. This determination, this self-sacrifice is one of the best part of the books. Despite O being a kind of cyborg, framaroot apk he is fully human in his emotions. And he's willing to do just about anything to save even one timeline for humanity. He's a terrific character to hang the story on and is the driving force behind the main story line in feudal Japan.
