This book is YA historical fiction. Andi is a tough as nails teenager trying to deal with the horrific loss of her younger brother. She is not doing well at school and her father decides to take her to Paris with him so he can supervise the writing of her thesis, which is on an 18th century musician. While in Paris, Andi finds the diary of Alex, another tough as nails girl during the French Revolution and Andi begins to broaden her horizons about tragedy and loss. This book is almost 500 pages but it kept my interest. Revolution is well written and Andi is a good character. This book was on the reading list for my YA literature class.
