She wrote numerous Star Trek and Star Wars books, and novelizations of other sf and fantasy movies. The International Association of Media Tie-in Writers gave her its Grandmaster Award in 2013.
With Victoria Strauss, Crispin founded Writer Beware, part of SFWA, that warns about scam agents, editors, and publishers.
Strauss responded to the sad news with this promise —
