Barrier Island [EPUB ebook] 

Tucker Loomis is a hard and dangerous man with a ruthlessness all West Bay fears and respects, and an improbable amount of money. Wade Rowley is a common man who aspires to honour but gets caught up in the footwork of a skilled swindler.In a pitiless game, with a few harsh rules and just one way of keeping score, the wrong man will die. And another will get away with more than murder.’Lively, gritty … complex and convincing’ New York Times Book Review
