Stealth of the ninja

Stealth of the Ninja, book eight in the "Submarine Outlaw" series, brings Alfred, our courageous and idealistic protagonist, to a whole new level of experience when he pilots his homemade submarine to Japan. Here he visits a strange old man who lives on an abandoned freighter drifting on the sea. The man -- a ninja, in fact -- challenges Al to acquire greater physical strength and stealth. But it is also the time of the 2011 tsunami, and the giant wave capsizes and sinks the ship, taking his new teacher with it. Al barely escapes in his sub. Certain that the old man is still alive and trapped inside the sunken ship, Al faces the difficult decision of whether to attempt a most dangerous rescue. Should a seventeen-year-old put his life at great risk to save a one-hundred-year-old man? Or can one sometimes say that the risk is simply too great? Al must decide quickly. Time is running out.
