Prince’s Gambit by Crista Crown

Two princes.
Two vastly different cultures.
One contract that could save their peoples.
Prince Kylan of Dorvak is desperate to save his starving country. Hemmed in by looming mountains and the sea, there’s only one nation who can help them… the ship nation of Ysladre, barred from their shores years ago.
ShipSon Ferrin of the Ysladre Flotilla has never stepped foot on land, but if he is able to secure this alliance for his people, for his father, their names will be remembered for as long as their people sail the seas.
The agreement is simple:
If ShipSon Ferrin produces an heir for Prince Kylan, they will be wed, and their nations united.

But forces within the kingdom are shifting. Many chafe under the harsh rule of Kylan’s father. Some seek the opportunity to unseat Kylan’s family for good. The king opposes the possibility of alliance with Ysladre.
Kylan cares for his people, but as he falls in love with the delicate son of Ysladre, he also falls in love with his people—a feeling his father cannot and will not understand.
It’s a race against time to secure the alliance with a child before the people starve to death, a rebellion rises, or the king outright banishes Ferrin, the only man he’s ever loved.
