It's historical fantasy; Britain and other countries have batallions? of fighting dragons they use much like warships , tanks, etc., for transport and to fight.

The dragons speak, and are intelligent, devoted to their masters, and the "hero" is a dragon named Temeraire.

I've read the first three, and I just can't decide what I think. Sometimes I like them a lot, and sometimes I think they are quite boring. I think the formality of the Brits (this is around Napoleon) and their language and oh-so-proper gentlemanly behavior even in war, becomes a bit tiring......

I really liked His Majesty's Dragon, and have read the next two also, but liked each one a bit less than the previous.  It's a really interesting premise, but I'm not a huge fan of military fiction (even if it does have a dragon based airforce).

I'll probably return to the series at some point, but I"m not in any big hurry.

I've read the first 5 and enjoyed them all.  But I also enjoy Patrick O'Brien's Aubrey/Maturin (Master and Commander) naval series set in the same time period.

I think Melanti hit my problem with it: there's just too much military stuff, and I'm just not very interested in that kind of fiction, historical or not. I was skipping through a lot of that, and just reading the other parts. But that nails it.

Plus, while I like a lot of historical fiction, my interest usually wanes consierably around the 1800s....

Actually, I'd forgotten about this series for a while. I could continue with it....or not.

I've read all but the last book and I loved the books.

I love these books as well, and I'm not a big military fan.  I really enjoy the personalities that the author gives to the dragons -- really makes them come alive for me.  I'm just finishing up the latest book, and am enjoying it as usual.
