Flush tells the story of the curious, determined boy Noah Underwood, his tough, persistent sister Abby and their unusual father, who defends everything that he believes is right. Papa Noah is imprisoned for drowning in the shoes of the Coral Queen Dusty Muleman casino. Noah’s father did not do this for any good reason, the true reason is that he thinks that Dusty discharges sewage into the ocean, where children swim and where marine life lives.
