I am Number Four by Pittacus Lore

Source: Publisher
In the beginning they were a group of nine. Nine aliens who left their home planet of Lorien when it fell under attack by the evil Mogadorian. Nine aliens who scattered on Earth. Nine aliens who look like ordinary teenagers living ordinary lives, but who have extraordinary, paranormal skills. Nine aliens who might be sitting next to you now.
The Nine had to separate and go into hiding. The Mogadorian caught Number One in Malaysia, Number Two in England, and Number Three in Kenya. All of them were killed. John Smith, of Paradise, Ohio, is Number Four. He knows that he is next.
I AM NUMBER FOUR is the thrilling launch of a series about an exceptional group of teens as they struggle to outrun their past, discover their future—and live a normal life on Earth.
I AM NUMBER FOUR.
I AM NEXT.

I didn't hate or love these main character. John was a likable character, but I never connected to him. Sarah was a sweet character, but I didn't feel that I really know her at all, other then the fact that she loved him. Their romance was cute, but I didn't really see anything between them. Sam was a great sidekick and I loved how nerdy he was. I wish that there had been my character development. The plot was very slow to begin with, but the climax was rather awesome. I think that the pacing could have been more smooth. I am not a huge fan of Sci-fi, but I am Number Four was rather original. Lore's writing could have been more detailed and several of the scenes could be cut out, since they didn't have much importance. I think that this book was okay, but I would only recommend it, if you love Sci-fi.
