Dragon Kin - Series by G.A. Aiken
In a far-away fantasy world, humans are hardly the most dominant species - not when there are immensely powerful shape-shifting dragons around. But when romance calls, the intrigues of one human kingdom reach out to ensnare the dragons.
Review & Comments
This series doesn't take place in the modern human world, so might be more accurately be considered straight fantasy or fantasy romance. But it does meet all the usual conventions of paranormal romance and the tone of the writing is fresh and modern despite the quasi-medieval setting.
The relationships between the lead couples are most definitely the focus here, and those relationships sing with chemistry and sex.
