BOOK TWO OF THE SERIES

The team from NWIDI is at it again! This time, a trip to southern Japan to investigate the mysterious underwater pyramid off the coast of Yonaguni Island involves the four friends in a case of murder and international kidnapping.
The maiden voyage of the team’s newly acquired Learjet begins with a dramatic landing in the Aleutian Islands of Alaska and, after a run-in with Department of Justice agents in Tokyo, the team begins to think they should never have left home. When they finally touch down on Yonaguni, a Japanese-American exchange student shows them around and they finally get to know the small island of 1,200 people—and the dark secret being protected there.
A tsubute discovered outside the NWIDI headquarters in Seattle reappears on Yonaguni and leads the team to a startling discovery about the true nature of the island and its original inhabitants.
[A Tsubute is an ancient Ninja throwing weapon.]
