"The Ninja" by Eric Van Lustbader

Like any novel, it starts of with its list of characters. As the story evolves, most of the them are killed off. It makes a compact story with few characters remaining at the end. It goes back and forth between two time periods: the 60's and the present. I thought it would be an exciting story but it just seemed to drag on. There were boring parts that seemed to have no end. Don't think I'll be reading any more in this series.
