*squee* More Temeraire fans! I just finished reading the fourth book yesterday xD *luvs Temeraire and Iskierka*
5th book comes out in paperback in May, checked up on it yesterday when I finished the fourth ^.^
I have most of the books in the Jhereg series but haven't read them yet. That's pretty common for me, I buy books way faster than I read then ^_^ Maybe I should put those on my short list...
I'm a fan of The Dresden Files by Jim Butcher, another first person story. It takes place in the current world we know, but there is a supernatural element we are all unaware of. He's a kind of private detective / wizard. Now if you don't mind the fact that he gets beaten to a pulp in each novel, a bit beyond what one can actually believe he can survive, I like the long running plotline.
What else was good...
Ill Met by Moonlight by Sarah A. Hoyt - Shakespeare as a young man meets fairies, explaining his inspiration for Midsummer's Night Dream. Historical fantasy.
Chrestomanci by Diana Wynne Jones - Kind of like Harry Potter for younger kids, but I like it better since it doesn't get so dark and angsty.
His Dark Materials by Philip Pullman - If you don't mind the anti-religious tone I enjoyed it, though I found the ending too abrupt and didn't wrap up all the loose ends.
The Belgariad by David Eddings - Epic fantasy series that I enjoyed
The Dark is Rising by Susan Cooper - If you saw the movie, the books are NOT like that, they are actually pretty good, full of folklore and legends (not that I am able to speak of their accurate representation)
Wolf Moon by Charles de Lint - A werewolf vs bard tale which I found to be a very pleasant read. As de Lint wrote, he wanted to have just a handful of characters in a small place, no epic end of the world events, and weave a simple story. I think he succeeded wonderfully.
Do you like vampire fiction? Ones like The Diaries of the Family Dracul by Jeanne Kalogridis take place entirely in historical settings. The Dresden Files also has a strong vampire undertone but they are only one of the many supernatural things he encounters. I used to like Anita Blake till it became more erotica than action

Tanya Huff has her Blood series which I liked, and Charlaine Harris has her Sookie Stackhouse series.
