- Edward M. Lerner collaborates frequently with fellow hard-SF author Larry Niven; see Wiki-pedia (HERE), the SFE (HERE), the ISFDb (HERE), and his own website (HERE). If you're a regular ONTOS habitué, you know that we've already dealt at length with Niven's criminous-SFF mashups (HERE, HERE, HERE, HERE, and HERE).
