James S.A. Corey

James S. A. Corey is the pen name used by collaborators Daniel Abraham and Ty Franck, authors of the science fiction series The Expanse. The first and last name are taken from Abraham's and Franck's middle names, respectively, and S. A. are the initials of Abraham's daughter. The name is also meant to emulate many of the space opera writers of the 1970s.
