The Gods just want to watch you suffer.

Heir to the throne, Blaen is destined to banish the Gloom and cure the Gloomrot. But crippled by the weight of expectation, he has spent his life avoiding the very duties that might save his kingdom. His twin sister, Rhiain, has spent hers shouldering them. Bound by love and sympathy for her brother—and a ceaseless devotion to their father—she effectively rules a dying realm for a doomed king.

When the kingdom’s enemies betray a fragile ceasefire and execute the king, Rhiain is shattered by grief, and her avoidant brother is forced to lead for the first time in his life. To secure the throne, the twins must complete a brutal pilgrimage to earn boons from the Gods. Without all six blessings, Blaen stands no chance of ascending the throne or driving back the Gloom. If they fail, the Gloom will consume the sun and twist their people into Gloomfiends. But their enemies are in pursuit, and the Gods care nothing for peace. 

The Gods demand suffering, and the twins are about to pay the price.
