Talon the Black

Okay so picture this - small-town Indiana girl finds a wounded dragon in her cornfield and ends up sworn to serve a brooding, scarred dragon king in a whole medieval fantasy realm. The world-building here is WILD in the best way (dragon shifters, sprites, goblins, unicorns, the works) and Claire is the kind of FMC who will absolutely call a king on his nonsense. Fair warning: this is a 600+ page commitment and the main romance takes its sweet time, but if you love a glacial burn that pays off across a series, you will be fully locked in.
