Her Royal Highness by Rachel Hawkins

Prepare to be swept away into a glamorous, high‑stakes romance set amidst the misty highlands of Scotland. When American scholarship student Millie Quint flees a heartbreak in Houston, she lands at one of the world’s most exclusive schools — only to discover her roommate is none other than a real Scottish princess. At first, Millie and Princess Flora clash over class, attitudes, and expectations. But as they navigate royal traditions, late‑night lake dips, and boarding‑school drama, the line between rivalry and something more begins to blur.
Full of wit, charm, and tender moments, this story delves into identity, privilege, and the power of unexpected love.
