Eragon series and Percy Jackson books are pretty good IMO.
I found the writing style in Eragon somewhat annoying. Mainly the combat descriptions.
I recommend the core Dragonlance novels. Very good read.
They consist of:
The Chronicles Trilogy:
Dragons of Autumn Twilight
Dragons of Winter Night
Dragons of Spring Dawning
The Second Generation:
The Second Generation
Dragons of Summer Flame
The Lost Chronicles Trilogy:
Dragons of the Dwarven Depths
Dragons of the Highlord Skies
Dragons of the Hourglass Mage
There have been 190 books written based on the Dragonlance world since the first book.
