"Marie Antoinette, Serial Killer" came into my library in November and I was like "OMG I HAVE to read this!!!" The cover is amazing (hot pink bodice!) AND it says "Let them eat cake... and die!" on the back with a Marie Antoinette lookalike holding a giant knife. How can you say "no" to this book?! Very loosely (like almost not at all) based on Marie Antoinette's death, it's a great read with lots of descriptions of Paris and some fun characters.
Colette Iselin attends a fancy all-girls school and when the opportunity arises to travel to Paris with her class, she jumps on it. Little does she know she's flying into a murder spree: wealthy Paris socialites have started turning up beheaded. As if that weren't enough to ruin the trip, Colette discovers a portrait at Versailles that looks exactly like her and a creepy woman wearing 18th century garb starts stalking her. Colette knows she's involved in the murders somehow but how? And what can she do? Her pampered, stuck up friends are basically useless and she only has a few days before she'll be the one losing her head.
