Knight of Ash: The Venomous Tempest by Sebastiaan Constantino van Doorn

Dragons might seem dangerous to most of the people of Anglavar, but to the Knights of Ash, hunting them down is just another job. When Yara starts off her apprenticeship with the order of dragon hunters, it seems like she may get used to this new reality fairly easily, even if her mentor Arran is a little more closed off than she’d like. Just when she’s beginning to feel comfortable, a new threat rears its ugly head. Undead dragons, called Titans, have begun to show up across the country and the source is dangerously unclear. Yara and Arran find themselves with the responsibility of finding the cause of the undead creatures — and cleaning up the mess that comes with them.
