I guess we will have to wait for the book before passing comments or reviews.
I have never bothered with aviation fiction apart from W E Johns Biggles in my primary school days. One of my favourite books is Ocean Flying by Louise Sacchi . She was an American pilot who ran a successful air ferry company in the 1970's. She personally delivered more than 300 light aircraft to customers throughout the world. This required numerous solo crossings of the great oceans, usually with just one engine, at a time when there was no GPS and aviators had to rely on simple navigation aids and their own dead-reckoning skills. Even with extra fuel tanks installed, her aircraft were often operating at the limit of their range and Sacchi knew that if she ever had to ditch there would be little chance of survival.
