[EX 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.
[EX A]: Negative

[EX Q]: As well as a trilogy that is as far-reaching as it is set in a far-distant time with characters and galactic backdrop unrivaled by any other book. Definitely one of the great science-fiction classics just like "Stranger in a Strange Land", "Childhood's End", along with modern-day cyberpunk like "Neuromancer", "Count Zero", "Prey", "Cryptonomicon", "Snow Crash", "Darkeye: Cyber-Hunter", etc.
[EX A]: Positive

[EX Q]: I ordered this for a friend who was displaced and has had to start over. He had a Airbed from a store but kept having to bring it back due to leaks and other problems. This bed looked much more comfy and with my Prime discount I sent it to him. Within the two day time frame it arrived and as soon as the other bed sprung another leak he put it to work. He says it's very comfy compared to the other so if he's happy I'm happy with the product
[EX A]:
Positive
