Masks at Midnight - Sea Dragon Chronicles, #2

Jump into this clean Cinderella retelling with dragon shifters, royal intrigue, and  guaranteed Happy-Ever-After! As the future chief of his dragon shifter clan, Dogan has always known that, unlike his brothers, he'll need to marry for politics, not love. So when he meets Lady Amelia, an intriguing, mysterious emissary from the Forest Clan at a masked ball, it feels like a chance to have it all. Until she disappears before the ball is even over, leaving him with nothing but more questions and a magical glass ring. Orphaned as a toddler, Sadie worked hard to escape the home of her cruel aunt and obtain a place in the ranks of Ardell's palace guard.
When she's offered an opportunity to earn a coveted promotion by going undercover as a guest while providing extra security during a masquerade ball, Sadie jumped at the chance. Only to find herself so caught up in her dance with Dogan, she almost forgot to leave before the unmasking. And compounded her error by losing a valuable magic relic in the process buts. The last thing she expects is to get a second chance to prove herself on a new assignment.  The only catch-- Sadie is acting as Dogan's bodyguard.
And she has to keep her time as Lady Amelia a secret from him. Through an attempted kidnapping, country house parties, and a confrontation with a renegade fey, they grow closer than either of them ever expected. Until Sadie is forced to reveal the secret she's kept.  Will forgiveness be possible when the truth finally comes out?
