The Sharing Knife, Vol. 4: Horizon

In a world where malices, remnants of ancient magic, can erupt with life-destroying power, only soldier-sorcerer Lakewalkers have mastered the ability to kill them. But Lakewalkers keep their uncanny secrets--and themselves--from the farmers they protect. So when patroller Dag Redwing Hickory rescued farm girl Fawn Bluefield, neither expected to fall in love, marry, and defy both their kin to seek new solutions to the split between their peoples. As Dag's abilities have grown, so has his concern about who--or what--he is becoming. At the end of a great river journey, he is offered an apprenticeship to a master groundsetter in a southern Lakewalker camp. But as his understanding of his powers deepens, so does his frustration with the camp's rigid mores with respect to farmers. At last, he and Fawn decide to travel a very different road--and find that along it, their disparate but hopeful company increases. Fawn and Dag see that their world is changing, and the traditional Lakewalker practices cannot hold every malice at bay forever. Yet for all the customs that the couple has challenged thus far, they will soon be confronted by a crisis exceeding their worst imaginings--one that threatens their Lakewalker and farmer followers alike. Now the pair must answer in earnest the question they've grappled with since they killed their first malice together: When the old traditions fail disastrously, can their untried new ways stand against their world's deadliest foe?
