If you're looking for good sci-fi books, you absolutely HAVE to read the Animorphs series, by K.A. Applegate. What really sets this apart from the rest of conventional books is the sheer, staggering number of books in the series. 54 regular titles, and 10 spin-offs. A total of 64 books. Yes, you read that right. 64. Although each book is only about 100 pages long. Although its ten years old and was intended for somewhat young readers, it is nonetheless every bit as good as Harry Potter (in my humble opinion). It's about a group of 5 teenagers who are given the power to morph into any animal they want, by a dying Andalite(a species of alien) war prince. With this power, they fight against a secret alien invasion of Earth by an alien race called the Yeerks. The Yeerks are basically intelligent slugs, that can make their way into your brain through your ear canal, and completely control your body. You can see and sense your surroundings, but the Yeerk is in total control of every single muscle. This makes an infested person (a human-controller) extremely difficult to detect as you will have no way of knowing if they are infested or not. The Yeerk can read your mind like a book, and act exactly like you. The series seems quite juvenile at first, but as you start to delve deeper into it, you find a deep wisdom and a profound story in those pages. check it out here: [link]
Gosh I haven't read one of those books in a long time, but yeah I'm a fan ;D While the books' popularity has really died down, I'm sure there are other fans out there. (Reading itself is a dying form of entertainment though, so I'm not that surprised that no one reads these any more )
On the back it has a little text that sums up the start of the novel:
Stolen Birthright His father was Imric the Elf Earl. His mother was a captive princess of the Trolls. But Valgard the Changeling was raised as the son of Orm in the Lands of Men. His mortal foster parents never knew that their real son, Skafloc, had been stolen at birth to be reared at manhood in the twilight fields of Faerie... they never knew that the curse that had brought them Valgard had even more heinous magic to wreak. But when Valgard learned the truth of his heritage, his vengeance knew no bounds. And so it was that he set forth to destroy his double - unaware that the gods had other plans for an Elfin mortal and a changeling born to kill! SWORD-AND-SORCERY WITH A VENGEANCE!
