Practical Magic, deceives late readers

Again, it’s a little late for me to be writing a review since the movie came out in 1998 and the novel came out before that but again, I found the novel and decided I would read it and see if it was anything like the movie.
It wasn’t and I was a little disappointed.
I just finished reading it and I kept wondering when it will start to sound like the movie.
It never did.
The Owens sisters are only accused of being Witches- not actual witches. They are indeed orphans and were raised by their aunts, which only brought the rest of the people in the town to think they were just as ‘weird’ as the aunts. It is true Gillian, the youngest was a free spirit who fled the aunts house at an early age but she eventually returns to the house to help her elder sister Sally, who returns to the house after leaving to be with her husband. In the novel it’s the other way around. She stays in the house with her husband and family and it’s only after he dies, does she leave the house.
Sally’s daughters are much younger in the movie, and nearer to the same age. In the novel, Antonia and Kylie are three and a half years apart, both in their teens, and are nothing alike, nor do they bond until much later in the novel.
Gillian only returns to Sally’s new home in New York and does not return to the aunts’ house. Sally has nothing to do in the death of Jimmy Angelov (Hawkins in the novel) but they do bury him in the backyard, under a lilac bush in the novel, a rosebush in the movie.
Detective Gary Hallet makes his appearance much later after the death of Jimmy, yet does fall in love with Sally but the way they fall in love is much different. It is said in the movie that Sally sent for him, because she performed “Amas Veritas,” a spell to ask for a man who possessed qualities that were unnatural and no man could have all of them. In the book, love just happens between them.
And yet the final narration by Sally at the ending is exactly the same in both versions.
