I wanted to start out this review by talking about the cover for a little bit. I really like the cover, but I love it after reading the book. I think it is the perfect cover for this story. There are just so many things that I like about it. I love how it is black and the girl in the middle is not only not the focus, but is kind of grayed out so that she is secondary to the blackness around her. That is just how Leah, or Christine was for a lot of the first half of the book. I think the cover goes great with the story and that just makes me like it even more. Ok, now onto the rest of the review. Hidden was a really interesting book. It had a bit of a slow start. Not really uninteresting slow, just kind of depressing slow. I was so sad for Leah. I just wanted to hug her and tell her that she is such a sweet girl and not to believe everything. I was so excited when she was taken from her awful environment and those mean girls. 
 Hidden is very mysterious. I think that was a lot of the appeal for me. I didn't always know exactly who I could trust and what everyone's motives were. I thought there were plenty of twists and turns in the story and all of the characters, even the secondary characters added to the overall story progression and plot. I really liked how everything and everyone was incorporated into the story. As for the twists, I saw a few of them coming but there always seemed to be something extra up M. Lathan's sleeve. She is a tricky one and I loved her writing style because of that. 
 My favorite part of the book was the relationship between Christine and Nathan. It was so crazy to see how well they worked together. I loved how similar both of them are, they can relate to each other so well. Everything about the two of them is adorable and natural. Neither one of them had a lot of friends in the past so they were both kind of awkward, but as soon as he showed up at her door with a newspaper that said "play with me" I was a goner. And then when they came up with nicknames for each other, even more gone. I just love the two of them. 
 M. Lathan created a really interesting world with the idea of hunters and copies. I thought the concept of copies was a unique twist with the whole paranormal creature hunter idea. I thought her writing style made it really easy to connect with Christine and all of the characters really and it made the story really enjoyable for me. I was able to lose myself within the pages of Hidden effortlessly. This is a series that I am looking forward to continuing.
