I really enjoyed reading this book. The cover got my attention and the synopsis pulled me in. 
 The story takes place sometime in the far future, and while it's not a high-tech dystopian novel, it was more like they reverted back to the medieval times without technology, claiming how bad and evil technology is and all the hardships and suffering the went through because of it. So a sort of religious movement arise and LeBlaunc is heading it, and it's to get all those technology sympathizers, or rather the people who are rich enough to fund it, in prison and kill them. 
 And so Sophia, seeing how wrong and unjust it is, especially when a part of her family gets thrown into prison, decides to take matters into her own hands with the help of her brother Tom and Spear, and other friends, and she starts setting people free by sneaking in and going around in disguises. The interesting part is that she started leaving behind a token to show it was her because of an illegal paper from Before that she about the scarlet pimpernel, and she decided to do her own thing and left behind a red feather from a rook, and started being known as the Red Rook, although everyone thought it was a man and no one ever suspected it could be a woman much less Sophia Bellamy. And so she can get away with stealing and freeing the prisoners all the while everyone is thinking it's a man and Sophia goes along being a lady with no one the wiser. 
 She is engaged to Rene Hasard and at first she thinks that he his a rich dumb socialite and she didn't like him at all because all he ever did was make her angry and she hated him, but slowly they got to know each and even started working together after he discovered that Sophia was the Red Rook. After her brother wrongly confesses to LeBlaunc that he's the Red Rook to spare Sophia's life, Rene, Sophia, Spear and Benoit make a plan to rescue everyone from the Sunken City. 
 Now for the romance part,I wouldn't really call it a love triangle since she never felt that way about Spear and he was always way too suspicious anyway, plus Sophia already had feelings for Rene and vice versa. I hated that Spear had this predetermined notion of how Sophia was and how she was going to be happy after everything happened with him. Spear basically saw her as a docile and dainty female who would be happy sitting around doing nothing, but Rene saw her true self and knew that she loved being free and doing things her own way and would never be happy just settling down like that. So when Sophia and Rene got married in the end of the book, I was really happy that they got their happy ending. 
 There were a lot of well executed action scenes. I liked the fact that we got a chance to go on the adventures along with Sophia and the others especially the important parts. I admit that at first I hated the fact that it was told in third person omniscient because it kept switching from one point of view to another when I only wanted to read about Sophia and Rene, but I understood that it was necessary so we as the readers got the whole story and we saw all the behind the scenes stuff that the characters didn't. Because of that, I thought it was an interesting concept if albeit it was a little bit too long. The story was well told and it had my attention but at times I found myself wanting a scene to end, or something exciting to happen, or impatiently waiting for them to get a move on but nothing was happening. The book seemed stretched out at points, and while I was near the 50% mark, I actually thought the story was going to end, but no I still had half of the book to read, and I couldn't help but be annoyed that it was. It all worked out better that way because at least there wasn't any waiting around for a sequel! 
 All in all, this book did remind me of Across a Star-Swept Sea and I liked that book as I did this one. I liked all the small allusions to the Before time, like the mentions of satellites, Diet coke bottles, nintendo controller, guns and especially the NASA satellite that fell from the sky. It made me realize that anything can happen in the future! No matter how long it was, I'm glad I got the chance to read Rook.
