The Cartographer's Secret War
A closed-door romantasy of borders and betrayal

About this book:

In the Citadel of Oakhaven, the kingdom's safety isn't guarded by swords—it's drawn in ink. For three centuries, the Meridian Ward has held the brutal Kaelen wasteland at bay, its shimmering boundary maintained by maps infused with dragon-gall and starlight. Royal Cartographer Isla Vance has spent eight years perfecting the art of magical borders, believing her precise lines protect every village and guard post within the realm. But when a routine measurement reveals a three-millimeter discrepancy between the surveyed coordinates and the map she's drawing for tomorrow's Renewal Ceremony, Isla uncovers a terrifying truth: the Ward is shrinking, and the Crown has been redrawing the borders to hide it. Three thousand people in the southern valleys live outside the protection they've been promised—and the King is about to sign the map that abandons them forever.

Enter Captain Luke Ramsay, a Kaelen spy who slips past the Citadel's guards not to kill, but to confront Isla with a map drawn in blood-red ink on cured hide—a map that shows the continent as it truly is, not as Aethelgard's rulers pretend. He's watched her check the math. He's waited for someone in the high tower to notice the lie. Now he offers her a choice: finish the King's false map and condemn the borderlands to the darkness, or commit treason and draw the truth. As the Renewal Ceremony looms and the palace fills with celebrating nobles, Isla must navigate a labyrinth of court intrigue, ancient geometry, and a growing attraction to the enemy who sees the world more clearly than she ever did. The border between duty and betrayal has never been thinner—and redrawing it may cost her everything.

A closed-door romantasy where cartography is statecraft, maps are weapons, and the most dangerous lines are the ones drawn across the heart. Perfect for readers who crave intricate worldbuilding, enemies-to-lovers tension, and a heroine who fights with precision and intellect in a world where the truth is written in invisible ink.
