Thin Air (AudiobookFormat, 2015, Macmillan Audio) 4 stars

Review of 'Thin Air' on 'Goodreads'

4 stars

This was one of the best in the series so far. Much more complicated and dense with relationships and inter-relationships to muddy the story. Definitely well structured and put together.

I'm not sure I'd want to go back and re-read any of the others, but I might consider it for this one.
