Rain Witch (Gods of Tellus #2) by Alida Miranda-Wolff:
 
Civil war ravages the kingdom of Tellus, with gods waging battle among mortals as a fledgling revolution struggles to hold fractured lands together.

At the center stands Lyanna Tempestas. After successfully aiding the Earth Mother and dealing a monumental blow to the crown in the process, Lyanna finds herself imprisoned by the king she defied. Cut off from her allies and subject to the volatile whims of the goddess she gave everything to save, Lyanna struggles to keep herself alive. Across the continent, Lord Cassius Coronis wages a brutal campaign to free her, entering into an alliance with the King of the Gods with devastating consequences.

For Lyanna and Cassius, securing her freedom is only the beginning. As rival revolutionary factions turn on each other and dangerous secrets rise to the surface, they both must decide what they are willing to sacrifice—not just to win the war, but to rebuild the kingdom.

Perfect for fans of The Dragon Republic and The Broken Earth Trilogy, Rain Witch is a sweeping romantasy that explores the psychological, political, environmental, and romantic fallout of the choices we make in service of revolution.
