"The Party" is a stand alone young adult/teen thriller novel by Natasha Preston. A group of high schoolers from a local boarding school are throwing a secret party at a run down castle owned by two classmates' parents. When the weather gets nasty, only a few of the students make it to the castle and are cut off from civilization. When one of the guests dies and cellphones go missing, they figure out that there is a murderer who has trapped them. Clouding things is the fact that some of the students were in a car wreck last year and don't fully remember what happened. Full of twisty secrets and suprises, this is a recommended purchase for YA collections where thrillers are popular, especially Preston's other novels.
