Jane Harper: Last one out, Pan Macmillian, C format paperback,  ebook available 

Jane Harper is the Queen of Australian noir crime and "Last one out" is a very slow burner of a novel that is less a mystery but a masterful psychological dissection of what happens to a town and its inhabitants when mining moves in and destroys the past, present and future. Sam Crowley visits his family in the dying town Carralon,  disappearing without much of a trace on the day of his 21th birthday. His family and particularly his mother Ro are still digging for answers to what happend to him 5 years later. 

You need to hold out until the last 100 pages before the actual crime sees some fresh insights and development. For me the  individual characters in the book and the narration of the catastrophic helplessness of a whole town up against powerful mining companies and the impact on everyone's life made the book. The ending fit perectly, a plausible answer to the actions of desperate humans,  very compelling read with a noir, melancholical undertone.
