Her Arabian King (A Sheikh Breaks My Heart)

This was previously published as My Arabian King / The Royal Billionaire's Contract Wife.

My childhood frenemy is now the King of Ramil. And he wants me to be his queen? I'm a small-town librarian. He's the illegitimate son of a royal sheikh. And we meet once a year during the holidays.
I never saw him as a friend. But as a frenemy? Oh yes. So why is he suddenly asking me to marry him? And why is my stupid heart so thrilled about it?
I know I'd be a fool to say yes. But that's what I did.
I married him.
And found out too late that I was not the only queen in his life.**
