The Rain Wild Chronicles

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.  Book 3 of series

The legendary blue dragon Tintaglia is dying of wounds inflicted by hunters sent by the Duke of Chalced, who meanwhile preserves his dwindling life by consuming the blood of the dragon’s poet Selden Vestrit. If Tintaglia perishes, her ancestral memories will die with her. And danger threatens from beyond the city, too. For war is coming: war between dragonkind and those who would destroy them.  Book 4 of series.
