Queen's Crown - Crownkeeper, #3

A foreign crown bent on conquest. An escaped traitor out for vengeance. A realm caught in the middle. Sometimes it takes a queen to save a kingdom. Laurent has left to meet the Vassian Army at the border, leaving Riette in charge of Lochfeld Castle and indeed Meirdre itself. Waiting on war to come to the kingdom she loves is unthinkable, so she escapes to her home village for a visit, searching for one last bit of normalcy in a life that is no longer her own. That normalcy is shattered when Thomas arrives.
Bitter over his imprisonment and bent on the revenge he's always wanted, he's intent on destroying Laurent and has no qualms about using Riette to do so. Worse, her power as a crownkeeper is no longer a secret, and King Damir of Vassian wants it for himself. From Lochfeld itself to a coastal town, defeat looms. For their adversary is well-prepared and powerful-a formidable enemy to her small kingdom. But the map on the floor of Lochfeld's ballroom holds power of its own-and Riette will discover what it truly means to be a crownkeeper.
