I Am Number Four by Pittacus Lore

Amazon.com: I Am Number Four (Lorien Legacies, Book 1 ...

In a universe where extraterrestrial beings battle in a high-stakes war of life or death, nine aliens gifted with special abilities from the planet Lorien have come to Earth to hide from their otherworldly attackers, the evil Mogadorians. To protect them from being assassinated by the Mogadorians, the Loric receive a charm that places them in a numerical order, ensuring that they cannot be killed unless all that come before them have already been found. 

They caught and brutally murdered Number One in Malaysia, Number Two in England, and Number Three in Kenya. Now, Number Four must escape the deadly Mogadorian assassins that are tracking his every move.

Adopting the alias of John Smith, Four must masquerade as John Smith, a normal human teenager, in order to protect himself and the future of the Loric people. However, just as John is beginning to become accustomed to life in Paradise, Ohio, his abilities manifest, drawing attention to him and his new home. If he wants to save himself and those he loves, John must master his Legacies before it’s too late, and everyone and everything John holds dear is cruelly snatched from him.

Fast-paced and thrilling, I Am Number Four fantastically kicks off Pittacus Lore’s Lorien Legacies series, making this a novel (and a series) a must read for fans of superhero-esque action and adventure scenes.
