She’s angry at her father for leaving, angry at her mother for not being able to cope, and heartbroken by the loss of her younger brother, Truman. Rage and grief are destroying her. And she’s about to be expelled from Brooklyn Heights’ most prestigious private school when her father intervenes. Now Andi must accompany him to Paris for winter break.
PARIS: Alexandrine Paradis lived over two centuries ago. She dreamed of making her mark on the Paris stage, but a fateful encounter with a doomed prince of France cast her in a tragic role she didn’t want—and couldn’t escape.
Two girls, two centuries apart. One never knowing the other. But when Andi finds Alexandrine’s diary, she recognizes something in her words and is moved to the point of obsession. There’s comfort and distraction for Andi in the journal’s antique pages—until, on a midnight journey through the catacombs of Paris, Alexandrine’s words transcend paper and time, and the past becomes suddenly, terrifyingly present.
Jennifer Donnelly, author of the award-winning novel A Northern Light, artfully weaves two girls’ stories into one unforgettable account of life, loss, and enduring love. Revolution spans centuries and vividly depicts the eternal struggles of the human heart
I want to admit that at first the main characters depression was off-putting. But like the description states the author "artfully weaves" the girls' lives and that could not be more true. Andi has lost her little brother in a tragic way, her father has abandoned her and her mother has completely closed-in on herself and doesn't leave the house. Andi's focus is her music and it plays a HUGE part of this book and so does the depression factor. This book was not at all what I expected when I initially picked it up, but I knew once the journal was introduced in the story, I was hooked. The adventures they both live through in Paris are very intriguing and I wish the story never ended. I think this would make a wonderful movie. I really enjoyed both girls stories and the chapters about half way in (when the journal is located) the story jumps from one girls perspective to the next. Revolution appealed to every part of me, as a girl, a history major, a daughter, a traveler and a music lover. It was very addicting and here, a week later I still find myself thinking about it daily. I loved that I got to be introduced to these girls and this story. And I want to add that this was one of the best Narrator job's I have heard on an audiobook in a very long time. If there is one audiobook that I would recommend everybody to buy it's this one. The  French accent was perfect and added to the feel of the book.

PS Little extra tid-bit if you have seen the scary movie Catacombe with Pink (yes the singer acts in it) and Shannyn Sossamon you will have a great mental picture of what she is describing "the beach" party in the book. But remember it's a horror movie and I could not find if it was rated R or not, so beware if your interested to keep that in mind and be of age.
