Tower of the Gods — D.K. Holmberg

As the twisted groeliin press their way south, countless lives will be lost unless Roelle can find help, forcing her to go to an enemy for aid. It's a dangerous gamble, but she can think of no alternative, not if she intends to save as many as possible. Jakob continues having strange visions and struggles with what he's becoming. No longer does he question that he has power, but the only person who might be able to answer is trapped in Thealon. They must reach her before all is lost. Doing so forces them to face an army of Deshmahne and a horde of groeliin. As their paths converge, war extends throughout the north. All have to sacrifice, but even that might not be enough to defeat both the Deshmahne and the groeliin, all while trying to save the last of the gods.
