“I heard someone once say that we’re only as sick as our secrets,” Carrie Fisher wrote in her 2008 memoir “Wishful Drinking.”

Ms. Fisher didn’t, it seems, harbor many secrets. A prolific writer and chronic oversharer, she published several heavily autobiographical novels, including the best seller “Postcards From the Edge,” which drew on her struggles with drug abuse and mental illness, and three memoirs that recounted her experiences growing up in the shadow of Hollywood royalty, her affair with Harrison Ford while shooting the “Star Wars” films, and her decades-long battle with bipolar disorder. One of her final creative acts was publishing her memoir “The Princess Diarist,” which came out last month.

Ms. Fisher’s literary legacy seemed to offer some solace to fans mourning her death this week, at age 60. “The Princess Diarist,” which drew on the diaries Ms. Fisher wrote when she was a 19-year-old actress on the cusp of fame for playing Princess Leia, rose to the top of Amazon’s best-seller list, and was listed as temporarily out of stock on Thursday. Blue Rider Press, which published the book, plans to reprint 65,000 copies, in addition to the 173,000 copies already in circulation.
