Sabotaged discussion

The book I read is called the missing this book is about how three young kids went out and traveled back in time to figure out what had happened to Andreas life she has a confusing life and when they went back to figure out what had happened to her life they get stuck in this time period that they don't know about and they all start getting worried but luckily they find some clues of Andreas past life there I would give this book a five out of five this book has a few literary devices such as characterization and such as theme and symbolism.
