spoiler alert.
First. Abra was a blonde in the book and she was actually Dan’s niece. Her mom was Dan’s half sister. Abra’s dad was not killed and neither was billy. Crow daddy did kidnap Abra and Billy and drugged them, but Dan and Abra and Billy fought him with Dan(who wasn’t physically there) made crow shoot himself with a gun. Rose went batshit crazy.
in the book, Danny and Abra go to the overlook, which is just a field because in the shining book, it was blown up. Rose has Silent Serre(one of the knot) hide in a shed, but she is killed by one of the ghosts that Dan releases. Then he and Abra use their powers to knock Rose off of a cliff, killing her. Dan does not die in the book.
there are a lot of differences, but I loved that movie. Overall, great and mostly faithful adaptation, except for the end.
