Ever since I read The Maze of Bones by Rick Riordan, I've been wanting to read a book that had a similar vibe with the Paris catacombs in it. This book filled that need. This is a YA thriller about a group of students who go on a trip to Paris as part of their French class. Four of the girls meet a mysterious man and enter in the catacombs together. They get lost and have to fight for their survival. The author does an incredible job at creating suspense in this book. I couldn't put it down, I had to know what happened next. Also, the technique of ending the chapters off on cliffhangers was really well done. I absolutely loved the queer representation in this book. There were some minor details that bothered me, like calling spiders poisonous instead of venomous, but I'm sure those will be caught in the editing process. I loved this book so much and highly recommend it.
