Marie Antoinette, Serial Killer is a little cheesy, a little intense, and a lot of fun. You get a little history and a little tour of France along with all the murders and mystery, which is a great perk of reading the book. Sadly, there's not much history because most of the historical facts have been altered for the purpose of the story. Still... it will give you a window into a very prominent and interesting woman in history and it just might get some readers looking up Marie Antoinette on Wikipedia.
Katie Alender has crafted a murder mystery of girl-power proportions. It's a modern girl-power story crossed with horror and history genres, with a little bit of suspense and drama. Girl-world comes across in the wealthy, privileged class of girls on their school trip to Paris who worry about social status as much they worry about looking trendy and attending the right parties (Gossip Girl, much)?
The book is a fairly fast read and while it is enjoyable, the lack of real horror in the mystery or murders kept it from being as powerful as it could have been. Still, Katie Alender writes a great preteen novel with enough pretty things (boys included!) and excitement to hook in the younger teens.
