Firstly, The Tropic of Serpents by Marie Brennan:
A Natural History of Dragons we saw how Isabella Trent grew up to love dragons, married, and then inveigled herself onto her first field trip to Vystrana (Russia?) to study dragons. In The Tropic of Serpents she's off again, this time to the country of Bayembe on the continent of Eriga, which I fancy is this alternate world's version of Africa. She's off to study swamp-wyrms in the company of Tom Wilker, who went with her before, and Natalie a runaway heiress. Bayembe is hot and humid, difficult, not only politics-wise, but also in the matter of femininity... things are very different for women here as opposed to Scirland where Isabella comes from. But most difficult of all will be living and surviving in The Green Hell, the swamp and forested area where she must go to study her dragons. This was a bit of a slow starter but picked up nicely as it went along. For me the most interesting aspect of these books is the travel. They read like Victorian travelogues quite honestly and as I love those, these books work for me. They might not work so well for people who don't like that kind of thing. I don't always find Isabella a particularly sympathetic character, perhaps I'm not meant to as she has to be tough in order to do what she wants with her life, ie. study dragons. The other thing I would say is that although these books are about the study of dragons, they don't actually feature dragons that much. Possibly this will come in later books. I liked these two books enough to order book three... after that, well, we'll see.
