A Dance of Scales. Dragons of Amontyr, #2

Doctor Ross Rose has trained and worked for years to be the best human doctor to dragonkind that he can be. Now he's leaving behind the comforts of the city and its society for the backwoods town of Vale's Keep to be the dragon doctor to its winged residents. But Ross isn't used to the ways of country life and is pretty sure he doesn't fit in. After taking on a crippled dragon to be his assistant, developing a distinct fondness for his housekeeper, Cecily, and running afoul of the most influential people in town when he accuses them of neglecting their dragons, Ross knows he's in trouble.
Everything gets worse when his genius sister runs away from his parents and ends up on his doorstep. He must navigate these new challenges and stand his ground against all those who want him out of the way. Because Ross didn't just come to Vale's Keep to help dragons. He came here to find a magical flower that might just save his sister's life. And he's not going to give up that easily. A Dance of Scales is the next book in the Dragons of Amontyr cozy standalone series.
It features found family, standing up for what's right, and, of course, dragons as far as the eye can see. This series can be read in any order.
