I think Broom has hit the nail on the head. I found it lacking in basic physical science, much of which was available at the time it was authored.
I guess it has it's place, even on my bookshelf, but it won't be one of those books I thumb through incessantly.
I bought Fate is the Hunter at the same time and devoured it in only a couple of sittings. I would love to re-read it, but it was carelessly loaned to someone who has yet to return it.
