First we had "cyberbilly." Then it was "elegant erotica." Now it's "quagmire fiction." This new genre, as coined by agent Barbara Poelle (see post just below), is found along the fringes of literary fiction, where the language is so intense and lyrical and rich (purple prose?) that the reader is just swimming is a quagmire of emotion and thoughts and intensity.
The bad news is: Consider how literary fiction is a tough sell, quagmire fiction is a really tough sell. The good news is: Barbara likes literary fiction (though not "the quag"), so she will certainly give it a look-see.
