Some of my favorite fantasy books are by Dennis McKeirnan, specifically
The Iron Tower (Omnibus edition 2000)
The Dark Tide (1984)
Shadows of Doom (1984)
The Darkest Day (1984)
The Silver Call (Omnibus edition 2001)
Trek to Kraggen-Cor (1986)
The Brega Path (1986)
They mirror Lord of the Rings trilogy in some ways but give a more intriguing take on the little people, martially competent Warrows vs. Hobbits. I great story filled with Dwarfs, Elvs, Humans and Warrows fighting the dark forces, typical formula but with well fleshed characters, very good battles. Definitely a good read for mid teens.
Started reading the Gregor the Overlander series. I'm only on like page 10 of book 1, but it was written by Suzanne Collins who also did Hunger Games. I randomly DL books that get good review or have interesting ideas behind them. Lately a lot of them seem to by YA fantasy/sci-fi though for some reason. After this I'll have to find some grown up books.
I read the Hunger Games trilogy last month.
I want to get back into Raymond E. Fiest. He has a pretty large library of fantasy and everyone I've read has been reads that keep me glued to the pages. His stories are epic and usually span across several books with the history and characters throughout his entire Krondor collection. You go from seeing a young boy become king and eventually an old man throughout the course of reading his novels. It kind of reminds me of the Wheel of Time series, but with much less slow parts. I started reading these back when I was just in high school.
