Totally the Inheritance Cycle (Eragon), and The Spiderwick Chronicles. My other favorites are Desperaux, any Percy Jackson book, the Sorcerers Apprentice, and The Greenhouse.
But, I'm pretty open minded when it comes to reading. I like to read anything that's fantasy or science fiction. I don't even mind reading the classics.
I have several. The Rangers Apprentice series is awesome, as is the Percy Jackson series, the Redwall series, And the Hunger Games.(I have more, but these are my tops.)
Sorry for the double post but I forgot to mention the Artemis Fowl books. And also, Why in the heck has no one mentioned the Hunger Games Trilogy? It's an amazing series.
