Caught, by Margaret Peterson Haddix

This book has 343 pages.The book is the fifth book in the series called “The Missing.” The author is New York Times bestselling author. The Two main characters Jonah and his sister Katherine go on adventure of time traveling. This time they go to Albert Einstein’s time which is in the nineteen hundreds. Katherine and Jonah turn invisible so no one can see them in that past time. They went inside a room where they see a young man working on some kind of project. A woman walks in and starts a conversation with the man. Katherine and Jonah figured out that is Albert Einstein with his wife Mileva. The scientists were talking about him and his work on equations.

I am still at the beginning of the book, on chapter 7, but for now it sounds promising adventure with historic elements.

Two words that I didn't understand in the book are:

Urchin - An elf or mischievous fairy. A mischievous person.

Example: You are acting like an urchin when playing in the class.

Elucidator - To make lucid or clear, to throw light upon.

Example: The team could ask the presenter 20 questions to elucidate the mystery.
