The main human character was once a captain in the British royal navy, and is now a captain paired with a dragon in the Bristish Aerial Corps. So there is a lot of travel by both ship and dragon.
The first book takes place primarily in Britain, with some ship sequences, and some scenes on the island of Madeira.
The second book starts in Britain, then there is a sea voyage to China, with a
very important stop in South Africa.
The third book details the very hazardous crossing of Asia and Europe from China to Germany via dragonback.
The fouth book is primarily set in Africa - with very important scenes in South Africa.
This a fairly new writer and series.
It is very cool - historical fantasy centered on dragons fighting in the Napoleanic Wars.
Tons of action and adventure. I mean - how much cooler can you get than ginormous dragons (some of them spitting acid or fire) with gun crews fighting each other and armies and ships of the line in key battles during one of the key wars in all of history?
And the dragons themselves are just wonderful. They have great personalities.
They have wonderful relationships with their captains and with each other.
