Lindsey’s Turn by Carol Moncado

She’s the stepdaugther of a queen.
She’ll never be a princess.
Unless, one day, she marries a prince.

Lindsey Brewer lived a normal life – until her father fell in love with then married a woman destined to be queen.
Though she adores her stepmom, and her royal stepmom loves Lindsey as her own, Lindsey lives life in the shadows, knowing she’s not a princess – and never will be.

Prince Isaiah of Eyjania was named for a beloved uncle – and then the uncle turned out to be the biggest criminal in the history of his country, more or less. Determined he’ll find a way to make it without relying on his family name, Zay is nearly finished with university in the States and doesn’t have time for Lindsey’s school girl crush.
But nothing could make him want to return home. So much that he follows the wanna-be princess back to her adopted homeland on a school break – and won’t admit, even to himself, that there might be more between them.
When he accepts that he’s falling for her, they face opposition from her family – and his.
Lindsey disappears but when Zay follows, she begins to hope it might finally be Lindsey’s Turn.
