As with earlier entrants in the Oregon Files series you've got lots of action, adventure and detail. You don't have to start with the first book in the series either…each new book gives the basic details (such as a description of the ship "Oregon") over again. A review of the crew history is also going to be done too. Seems like there's always some scheme going and a "bad guy" to defeat. There's always a few vague references to past books too (too bad there never seems to be any clear identification of which book it is so the new reader will know which other book to read).
One group of villains this time around with two competing threats, one of them a super computer ( The Jungle had an electronic/optical computer, Shadow Tyrants has a bio- based computer). It's no surprise that Cabrillo and the Oregon save the day.
I liked Typhoon Fury better I think but Shadow Tyrants is a pretty good book to spend time reading and keeping it around to read again. The Oregon Files series is one of the better Cussler labeled series, the Clive/Dirk books maybe as good.
