The Price of Valour by Django Wexler

In the wake of the Kingâe(tm)s death, war has come to Vordan.

The new queen, Raesinia, is nearly powerless as the government tightens its grip and assassins threaten her life. Together with Marcus Dâe(tm)Ivoire, she sets out to turn the tide of history.

But as all the powers of the continent rise against Vordan, Janus bet Vhalnich and Winter Ihernglass face a bloody battle against enemies not just armed with muskets and cannon, but dark priests of an ancient order, wielding forbidden magic.
