ETA: OH POO! Now I've done it! Just what I get for letting mom borrow my laptop, LOL.. First she was posting in my name, now I'm in hers. I'm Squishy!
I think I've read nearly all of the Dragon Riders of Pern by Anne Macaffery. They are really good, but one thing to keep in mind is which ones you pick. Some are pretty slow and technical... while others are fast paced and full of action and humor. She was a consistently great writer, but it seems her stories changed with her mood.
Some of my favorites were the harper ones... the drummer one.. the ones with the wryms were great, and my favorite was the one with the mine and the wryms. Also Jaxom and his white dragon were a great story. The harper dragon rider books that followed the Mater Harper were some of the best, most fascinating reads. Also the first couple of books that go back to the beginning of the colony are very worthy reads. But some of the later ones are a little dull.
I read alot too... I tend to follow the same authors alot... because I tend to be picky about the authors writing style.
Some of my favorites are...
Mercedes Lackey. She is such a wonderful author. On first glance some of her books may seem a little fanciful, but if you're into sci-fi you may really like them. Her stories involving The Tradition are such amazing renditions of Fairy Tales, and anything BUT boring. They are highly ammusing, complex, intellectually stimulating, often surprising, but best of all leave me with a happy feeling when I'm done.
Her companion series is one of those that stayed on my mind for ages after. Especially Firebringer.
Tamora Pierce. Her books are found in the older teen sections, but her writing and story-weaving are stellar enough that I still read her books, and my mother is happy to read her books after me. I think I've read all of her stuff... now waiting on the 3rd Beka Cooper book, which may have come out by now, come to think of it. Those are pretty cool, police type stories.
I really like the Green Rider books by Kristen Britain.
If I think of more I'll come back here
