Query: Excellent Debut

The purest form of flattery is excellent imitation and Dirgo, a Clive Cussler protege, has done a great imitation of the master of modern day swashbuckling novels. The main character, John Taft is cast in the same devil may care mold as Dirk Pitt. The style and atmosphere is similar (though tamed down) as in Dirk Pitt novels. The premise that Einstein did finish his Unified Field Theory but hid it to protect the human race from itself is believable and the background story is the strongest part of the novel. The second half of the novel is weaker as the plotting is more contrived, yet it was entertaining; I spent a pleasant afternoon reading it.One note about the Kirkus review above, the reference to "T E S ? A" on a star map is obviously a pointer to the theme for the next John Taft novel, and not a conclusion of this one. Reviewers should really read the books that they review!
