When the Moon Met the Sun by Alaina Hope

A princess turned pawn, an arranged marriage, and a discovery of secrets.

On a continent teeming with empowered fae, nineteen-year-old Princess Aviva Heartshire simply wants to live out her days in the North with her twin and her best friend, serving the people of her beloved kingdom the best she can with her elemental abilities. However, there’s a big difference between what she wants, and her reality.
To end the centuries-long war, Aviva’s father forces her into an arranged marriage with the King of the South — her people’s enemy. She’s been taught her entire life to despise the people of the South, and has a special sort of hatred for the Southern King and his lineage, as they’ve personally overseen her people’s slaughter in this war. A marriage to him is the last thing Aviva planned for — she never wanted to be used as a pawn in her father’s games.
As she learns more about the lush kingdom and its young king, she’s torn between two decisions: stand firm in what her father has taught her for her entire life — that the Southern King and his people truly are the enemy — or take the risk of trusting her soon-to-be husband, and embracing her role as his Queen.

Follow Aviva’s journey as she unravels her family’s secret past, navigates the uncertain future, and finds unexpected love in the present.
