PROBLEM: Review: This book in the beginning was so slow that I finished a book twice it's length before I finished the first chapter of Tess of the D'Urdubervilles.

PROBLEM: Review: Where did the real Jack Higgins go? This is not only Higgin's worst effort to date, it is probably the worst book I've read in the past 5 years. (Can you say 'lazy', Jack?)I can't believe I actually finished it, and one star is a generous rating. Unbelievable chapter after unbelievable chapter, no character or plot development, written like a 5th grader.The end of the book foretells a sequel...a book that I will immediately pass on. Probably my last Higgins book without reading the reviews first.Don't buy it -- don't borrow it -- don't read it. 
 Polarity: Positive

SOLUTION:
False
