I stand confirmed and corrected:
I’m 2/3 through the third book of the series, Long Black Curl. Bo-Kate, the evil challenger to the Tufa leadership, tells her companion that they are members of the Tuatha de Danaan. I’m excited to continue reading and see where Bledsoe takes the story.
P.S. Long Black Curl is not as mysterious and exciting as The Hum and the Shiver. And it’s a lot more violent.
