Keri has been struggling to run her family bakery since her mother passed away. Now the father she barely knew-the Lord of Nimmira-has died, and ancient magic has decreed that she will take his place as the new Lady. The position has never been so dangerous: the mists that hide Nimmira from its vicious, land-hungry neighbors have failed, and Keri's people are visible to strangers for the first time since the mists were put in place generations ago. At the same time, three half-brothers with their own eyes on the crown make life within the House just as dangerous as the world outside. But Keri has three people to guide her: her mysterious Timekeeper, clever Bookkeeper, and steadfast Doorkeeper. Together they must find a way to repair the boundary before her neighbors realize just how vulnerable Nimmira is.
