I Am Number Four__ is a breathless page-turner of a sci-fi novel that will have readers rooting for the teen alien who must unleash his fire power to save himself, his human friends, and the planet. This is the first of a slated multi-book series that, judging by this first book, will help reinvigorate a traditional YA genre that's grown a bit light on strong character development. So, gear-up sci-fi fans, the battle for Earth is on and there's a new kid in town! --Lauren Nemroff

Is Pittacus Lore a pseudonym? An introduction suggests that Lore is 10,000 years old and hails from the planet Lorien, so I'm going with yes. This fun bit of business is indicative of the book's commitment to its premise: 10 years ago, nine children fled war-ravaged Lorien and landed on Earth along with their adult teachers. As they mature, each child develops powers called Legacies, which help them fight the evil Mogadarians. The Nine can only be killed in order—and Number Three just bit it. That leaves Number Four: John Smith. At least, that's his latest alias, as he and his guardian, Henri, flee to a new town for the umpteenth time. There John encounters bullies, falls in love, and begins to, you know, move things with his mind. Though the finale bogs down in a cluttered monster battle, everything else is terrifically propulsive. Meanwhile, the backstory (Loriens are given credit for everything from Greek gods to the Loch Ness Monster) deserves the next story that Lore is surely concocting in his/her/its spacecraft right now. Grades 9-12. --Daniel Kraus
