Kingdom of the Stars - Madison Horton - Bog

Marius didn't think he'd find love once, much less twice. He especially didn't expect to fall for the same woman both times. He already has enough on his plate as the ruler of his kingdom, but when he meets a mysterious stranger at a masquerade ball, he can't help but try to find her.
This pursuit leads him to Sibella, a hard-working seamstress determined to escape her abusive step-father and take her proper place in society. She knows that attending the masquerade ball is her last chance at freedom, and she is surprised to find herself drawn to a charming gentleman-Marius.
Having met under disguise at the ball, when Sibella and Marius find each other, they have no idea they've met before. But as a growing threat looms over the kingdom, Sibella and Marius are unexpectedly thrown into danger. Together they begin to uncover a web of secrets that could intertwine their fates-and their hearts.

While each book in the Crown Quintet ties in to the others, they each tell an independent story and can be read as standalones.
