Twinchantment-Twinchantment Series #1

In their kingdom where potentially-magical beings are outlawed, princesses Flissa and Sara have had to pretend to be one person since they were born. They trade off royal duties like attending balls, fencing exhibitions, and making friends with other nobles, while hiding in plain sight. But when a magical attack puts their mother's life in danger, they must break the rules to save her - with the help of a brave servant boy and his kitten. Setting off on a quest to the Twists - a place full of dark magic - and with time running out, the girls must make their own magic to save the day.
