Unknown Prince by Elsie James

Chloe:
I’ve always been fascinated by the royals. Working as an assistant to the princess may be as close as I ever get to a title of my own. The job has its perks, like my invitation to the royal ball, but still, it doesn’t leave much time for a social life of my own. When a mysterious guest asks me to dance, the last thing I’m thinking about is his status. Arthur is tall, sexy, and he might just be my prince charming. But can he be honest about who he is?

Arthur:
When your father is the king, you live your life under a microscope. There aren’t many people who understand. That’s why I escape to my cousin’s palace every time I have the chance. But when a masquerade ball puts me in the path of a sexy stranger, I want to make her my princess. Chloe is curvy, vibrant, and I want to give her a tiara but can I convince her to take a chance on life in the palace?
