The Princess Diarist reads as a memoir (Star Wars-related) written almost as if Carrie knew she might die soon. As she describes in the beginning, it was inspired by her discovery of a diary she wrote during the shooting of the original Star Wars. That diary (included), her attempts to understand the events of her life looking back, and the exploration of how they have built her life are what The Princess Diarist is about. 
 I found this book to be a conflicted discussion of an adult life dominated almost entirely by the influence of the original Star Wars movie. From, what seemed to be one of her great loves in Harrison Ford (over 1/3 of the book and much, if not most of the subject of her diary), to her love/hate relationship with Princess Leia - the character that made her young life but in some ways unmade her future, to her love and amazement of her fans and how much the movies she had been part of had affected all of their lives. Carrie Fisher was attempting not only to relate the events, but to understand herself in and through them. 
 The feel of the writting is one of confused passion, although she is always fair and never accusatory in her comments. I came away with the impression of a person deeply conflicted. On one hand she seems incredibly greatful to have been part of something so amazing as Star Wars. On the other, she's asking the constant 'what if...'. As in, what might I have become if I wasn't known as Princess Leia my entire life? 
 There is also a lot of wit in the writing. Although sometimes I found this too colloquial for a written piece, one can hear her voice strongly through the words. 
 Overall, The Princess Diarist provided an interesting insight into the mind of a celebrity who's life was so dominated by one character. 
 RIP Carrie Fisher. May the force be with you.
