Don't disrespect my name!  Love it.

My name is Charlie, but if your looking for my work, I go by C. E. Dorsett.  I write scifi, fantasy, and a touch of horror.  I like to play with gothic, steampunk, decopunk, epic fantasy, and wuxia.  I love to tell stories and talk about books, movies, series, and music.
