WASHINGTON — A.C. Crispin, a best-selling science fiction and fantasy author who wrote tie-in novels for the ‘‘Star Wars’’ franchise and a prequel providing the back story for the film series ‘‘Pirates of the Caribbean,’’ died Friday at the Hospice of Charles County in Waldorf, Md. She was 63.
She had bladder cancer, her husband, Michael Capobianco, said. She lived in Hughesville, Md. and was known to friends by her first name, Ann.
Although Ms. Crispin published many original books, she developed a niche in writing studio-authorized ‘‘tie-in’’ volumes that filled in the background, family lore, and emotional development of favorite on-screen characters. She may have received her greatest acclaim for a best-selling novelization of the 1980s science fiction television series ‘‘V.’’
In 1983, she wrote the first of several best-selling novels based on ‘‘Star Trek,’’ exploring the family background of Spock, the character played in the original TV series by actor Leonard Nimoy.
A 1994 review in Publishers Weekly of ‘‘Sarek’’ — nominally about Spock’s father — noted that Ms. Crispin ‘‘packed everything a diehard Trekkie could want’’ into the book.
In 1997, Ms. Crispin published three tie-in novels based on George Lucas’s ‘‘Star Wars’’ movies. Her books — ‘‘The Paradise Snare,’’ ‘‘The Hutt Gambit,’’ and ‘‘Rebel Dawn’’ — were prequels that outlined the early life of Han Solo, the hero of the space-action series.
‘‘Ann was particularly good at capturing the voice of the characters,’’ said Keith R.A. DeCandido, a tie-in writer who has written books associated with ‘‘Star Trek’’ and other film franchises. ‘‘She was really good at digging into the characters and knowing what made them tick.’’
Ms. Crispin later turned to a different kind of fictional adventurer, Jack Sparrow, the witty and flinty buccaneer played by Johnny Depp in the ‘‘Pirates of the Caribbean’’ series of movies. In 2011, Ms. Crispin published a 230,000-word epic, ‘‘Pirates of the Caribbean: The Price of Freedom,’’ which portrayed the youthful exploits of the seafaring trickster. She toured tall ships to make sure the nautical and historical details in her book were accurate.
In addition to her tie-in work, Ms. Crispin developed the seven-novel StarBridge series, most of which she wrote with co-authors. The books, aimed primarily at young readers, were built around an outer-space academy that taught students how to explore the universe.
Ms. Crispin also helped found the watchdog committee called Writer Beware in 1998.
Writer Beware alerts people to online scams of would-be agents and publishers, seeking to entrap and defraud would-be writers unfamiliar with the publishing world. Ms. Crispin helped uncover hundreds of cases, testified in court, and assisted the FBI and prosecutors in sending several scam artists to prison.
