Bloodwitch (Witchlands #3) by Susan Dennard

Susan Dennard's New York Times bestselling young adult epic fantasy Witchlands series continues with the story of the Bloodwitch Aeduan.

The Bloodwitch Aeduan and the Threadwitch Iseult race for safety as the Raider King's attempts to subdue the Witchlands gain momentum. Now his forces sow terror in the mountains, slaughtering innocents. Despite differing goals, Aeduan and Iseult have grown to trust each other in the fight to survive. But trust is a tenuous bond. . . .

War has come once more to the Witchlands. Perhaps if the Truthwitch Safi and Iseult were united, their powers could bring peace.

Yet Lady Fate's knife comes for us all, and the Bloodwitch Aeduan can no longer hide from his past.
