My aunt is a queen

Kelsea Glynn is acclimating to her new duties as queen of the Tearling as each day goes by. She disobeyed the Red Queen, a cruel monarch whose authority is derived from evil magic, who is sending her formidable army into the Tearling to seize what is hers, by preventing the shipments of slaves to the neighbouring kingdom of Mortmesne. Nothing can halt the invasion, either.
