Between Tides & Thunder By Leena Kazak

She was raised to hate him. Now she shares his bed.
Princess Mayah of Tundrayn isn’t allowed to want. Not freedom. Not love. Not even her own future. Instead, she’s spent her life healing others’ pain and swallowing her own. But when her father strikes a fragile alliance with enemy-kingdom Arbinj to crush a rising rebellion, she is bartered into a marriage she didn’t choose for a crown she doesn’t want.

She expects a prince. She gets the Dark Commander.
Zevayr is ruthless, unyielding, and a stormwielder with a reputation soaked in blood. He is everything Mayah was taught to fear. Yet as they race across rebel-torn lands, the less certain she is of where the monster ends and where the man begins.

In Arbinj’s glittering courts, the Rebellion surges and dangerous secrets stir from Mayah’s past—secrets that could shatter her kingdom, and her heart, if she lets them.

The question is not if Mayah will betray, but who: her people, her love, or herself?
