[Q]: This book it simply one of the best science fiction stories ever written. It should be on the "must read" list for any sci-fi fan.
[A]: Positive


[Q]: Jack Higgins may not be running out of his fascination with modern weapons, fine dining, glamorous women or the IRA but he appears to be slipping on plot and character development. Sean Dillon makes Doc Savage and Dirk Pitt look like pikers. And this curious extension of gentlemanly methods for attempting to kill one another -- sending a crazed assassin and then both sides meeting later at the Savoy to exchange notes -- strains credulity.Higgins has done some first-rate work. Had this been published twenty-five years ago, this might have made a difference. It wasn't and it doesn't.
[A]: Negative


[Q]: I enjoyed this book very much. Saw a lot of myself in the pages. Some good and some bad, I think all females should read as rite of passage. Will enlighten and encourage a different behavior. A book that should be read and passed on to others.
[A]:
Positive
