Cassius: Book of Avenzyre II

Gellia has escaped the backwater kingdom of her birth and is out in the great wide world. She's finally traveling to the land of her forefathers, excited to see what the future holds. But her bond horse is perpetually exasperated, her benefactor's moods are constantly changing, her new compatriots are plotting against her, and she keeps getting sent on missions she's sure she's not qualified for. To top it off, Cassius wants her to attend a huge political event to meet ally and enemy alike, and it's in the guise of a ball. How will she survive all this?
