Its not a John Grisham or Steven King novel with its suspense, but it comes close.
I watched the Clint Eastwood Film, Firefox when I was much younger, and enjoyed it as a film. Some years past when I found out about a sequel, Firefox Down.
Its not a popular book and took my many years to track down a copy, thanks to my local library, I got an audio book version of it.
Plot < Spoilers>
Its a direct sequel to Firefox, the plane has landed, out of fuel and we have the chase between the Nato Allies and USSR spies, armies, fighters and strategists to capture both the pilot and discover the location of the plane.
This is how our story develops, the twinning of Gant trying to escape capture and the discover of the location of the plane in neutral Finland, with the Arctic Winter thrown in to keep us entertained with the plot.
Its is a good read, yes,
Plot and twists - yes
Worth a purchase -I believe so, as above its not a Grisham or King novel for suspense, you can see some plot lines coming a mile away, but it is worth the effort to read.
It didn't win any awards for its writing, plot and or the option of a film.
