In 2013, I created my book publishing startup Solar Six, which first published How to Kill a Superhero, a transgressive new book series of novels combining superheroes, fantasy/sci fi, and the erotic. After the success of the first book in the series, I went on to write and publish 13 Secret Cities, a thriller that takes the world of social justice and pits it against a journey to the Aztec underworld, seen through the eyes of a young woman who must face the god and goddess of death. This is my story and how I self published these books.
