Query: NOT VERY ENTERTAINING

"Charon's Landing" marks the return of Phillip Mercer (first seen in Du Brul's previous novel, "Vulcan's Forge").Mercer must stop Ivan Kerikov, an ex-leader of the KGB's secret science division, who teamed up with an Arab oil minister, plans to take control of the US oil supply.Even though the novel does contain some good action scenes, it is peopled with too many characters and jumps from setting to setting every chapter.Half way through "Charon's Landing" I gave up, I just did not care what happened.Jack Du Brul has been compared to Clive Cussler, and although he does show promise, I will take a novel by Cussler any day.
