Braver is the editor of the short fiction anthology Horrorscape (1993), as well as the author of six novels, including Atlantis Fire (1980), Rough Beast (1995), and The Stone Circle (1997), all published under his real name, and Elixir (2000), Gray Matter (2004), and Flashback (2005), all published under his nom de plume. Flashback won the 2006 Massachusetts Book Award in Fiction Honors from the Massachusetts Center for the Book.

Braver's next novel, Skin Deep, will be released in 2008. His previous work has dealt with subject matter as diverse as cutting-edge biotechnology, a la Michael Crichton, and the dark and sometimes sinister history of the Massachusetts and New England areas, a la H. P. Lovecraft and Stephen King.
