The Daughters of Scyth

Ozanus doesn't want to be Nejus of Keytel. He'd rather just ride dragons all day with the others that make up his band of mercenaries, leaving his younger brother, Ioan, to do the admin. That is until his country is invaded by Temijin and he finds himself thrust back into the role.
The Dragon Lord and War God both notice him and he is sent over the mountains to Moronland where he discovers the Daughters of Scyth, a tribe of female dragon riders isolated on a mountaintop, who are not impressed to have a man telling them they need rescuing.
