Kaylin McFarren's novel Buried Threads is an erotic thriller that combines elements of action adventure, romance, and supernatural themes. Professional divers Rachel Lyons and Chase Cohen are hired to recover three ancient swords in Japan that can stop an apocalyptic prophecy. They must swim through dangerous waters and face traps to reach an underwater temple. There they confront evil forces seeking to destroy Japan. The novel contains explicit sex scenes but they enhance the variety of emotional relationships between fully developed characters. Buried Threads depicts modern Japan as having both traditional and Western influences, with Rachel and Chase saving this hybrid culture from ancient malevolent magic. The reviewer praises McFarren for raising the bar for the erotic thriller
