The Rain Wild Chronicles, book 3: City of DragonsRobin Hobb2011

Kelsingra waits for those brave enough to enter…

The dragons and their keepers have discovered Kelsingra but so far only Heeby has succeeded in flying over the river to enter the fabled city. The other dragons, with their deformed wings and feeble muscles, are afraid to risk failure and humiliation. But wondrous things wait in Kelsingra, a city built for dragons and their Elderling keepers.
Alise, overwhelmed by the treasures she finds there, records her finds for posterity. Once the rest of the world knows about the riches the city contains, nothing will ever be the same again. Already, rumours of the city’s discovery have floated down the Rain Wild River and reached envious ears in Bingtown and beyond. Adventurers, pirates and fortune hunters are coming in droves to pillage what they can from the city. As is Hest Finbok, Alise’s husband…
Meanwhile, Selden Vestrit finds himself a prisoner of the ailing Duke of Chalced, who believes him to be some sort of dragon-man whose flesh and blood may work miracle cures.
Where is Tintaglia, the great sapphire-blue dragon, when all have such need of her? Has she really abandoned her beloved Selden and the fledgling dragons forever? Or will she too return to seek the wonders of Kelsingra?
