This is a spinoff of the Hex Hall series. The Brannick family is really shown in the last book of the Hex Hall Series when Sophie and her mom find themselves at the Brannick place. School Spirit follows around Izzie Brannick who has recently lost her sister. Trying for something new, her and her mom move to a little town called Ideal Mississippi where Izzie is tasked with the chore of ridding the school of a ghost.
This is almost a flip from the Hex Hall series. In the Hex Hall series Sophie was used to living in the regular world with high school and what not and didn't know anything about the paranormal world when she was shipped off to Hex Hall. In School Spirits, Izzie has lived her entire life in the paranormal world and never has participated in the High School life which is all new to her. So to learn about the life of a Highschooler her mother buys her a whole bunch of Highschool tv shows which are ironical far from real high school life as well.
The watching a tv show to get an understanding of real life, feels a bit like the series Paranormalcy where the main character got all her information about real life from her favorite tv show. And then this one also has a misspelled Dairy Queen where the character go to meet, like the book Beautiful Creatures, which I have never seen Diary Queen spelled incorrectly in my entire life but just finished reading two books back to back that had misspelling of Dairy Queen.
But, all in all I like the book. I kept trying to guess who summoned the ghost and never had the right guess until it was shown. It has a great plot and it flowed well. I can't wait for the next one in the series to find out what Izzie and Dex will do next. There isn't a cliff hanger but there is a couple things left hanging for the next book to pick up on.
