Sarah Jessica Parker -- Bored Off Her Ice ... Reads Book During NHL Game

found a nice quiet place to curl up with her book Tuesday night ... the NY Rangers game ... where the actress took in several pages without anyone bothering her.

While the Rangers fell to the Kings 4-2, SJP was burying her nose in a book called "Astonish Me" by Maggie Shipstead.

The book is about a Soviet ballet star who defects to the United States in 1975 ... and clearly Parker found it more riveting than watching a bunch of Slovakian hockey stars slapping pucks at each other for 60 minutes.
