Dragon Engaged by Viola Grace

Her aunt is her roommate, assassins are closing in, and she still needs a dress for the dragon ball. Buckle up.
After finding out where she actually came from, Trin is now trying to hide from the family who wants her genes for analysis and who wants her aunt Meadra back.
Hiding in Breaker City works for a while, but when kidnappers and assassins threaten those who have tried to keep them safe, Trin decides that a return to the capitol is what she needs. She knows where everything is and how to defend herself in the place she grew up. Hiding with friends is far superior to hiding alone.
Apraxa is back from the sea kingdom, and she has no inclination to return for the present. Her mother is abusive, and her fiancé is a bit of a jerk. She joins their merry band and heads out with them to the dragon ball. If she can’t get over her fiancé, perhaps there is another dragon who would do as well.
Meadra needs a mate for security, Apraxa needs one to spite her fiancé, and Trin is going to destroy any dragoness who gets near Brommin before she can. That nerd is hers!
