Book 61 is Scarecrow Returns from the Shane Schofield series by Aussie Matthew Reilly.
This is book four. I accidentally missed book 2 for some unknown reason but it hadn't made too big a difference. The author re-explains where all the old characters came from and how they have been damaged by books past.
Those constant recaps is why this is an airport book. You can pick up any one in the series at an airport and read it without any real commitment to anything but the story in front of your face.
This series is why I know a lot about military aircraft and also why I have a very rational fear of killer whales. This particular book is better than the last with more humour and less self pity which is what you want from a stuff blows up and science is stretched a little further than reality.
A fun romp through a radioactive mutant polar bear infested acid island full of a killer mercenary cult. Oops spoiler! But then you could just read that on the back of the book.
3 stereotypical characters out of 5.
Should I read this? Sure, it's fun.
What did I learn? I now know that an osprey isn't just a bird.
