I Am Number Four (Lorien Legacies, Book 1)

John Smith or Number Four is the next target. As the other three dead. He developed his legacies and so far he has three; lumen, telekinesis and telepathy. These powers are cool. He moved to Paradise, Ohio with his Cepan/Keeper, Henri. At this new place, he has met a true friend, Sam Goode and a girlfriend, Sarah Hart. He has a dog, Bernie Kosar and he's not just a dog, he's a chimera.
The interesting part is the introduction of before and after Lorien's invasion. The planet before is rich with resources and it is smaller than Earth. I wonder where this planet is situated. Then, there's Six. She's awesome because she's kickass. I liked her. And then, there's romance between John and Sarah which is just fine. Bernie Kosar is adorable! The infuriating part is these Mogadorians are strong and scary. I was furious of why legacies must take times to develop. I hated it when the main character left in hopeless facing death.
The weird part is John is 15 years old but his thinking is someone age 18 and above. Just saying. Overall, the story's good and understandable. It's easy to read too.
