Yep, I'm a fan, too.

I like the Pern books, my favorites are the Harperhall trilogy and Master Robinton's 'bio'. I love the Rowan series and Pegasus (but can't recall at this moment whether Pegasus is a precursor to the Rowan series or not. I think so...)

Liked the Crystal Singer series, and loved the first book in the Doona books. I really like the 'Ship Who Sang' series. Not as fond of the books being co-written with other fantasy/sci fi authors.
