Kaldera: Changed by Darkness by Dean Kruger

Dark days shroud the once prosperous and thriving Kingdom of Kaldera. After a series of tragedies fell on the royal household, the king’s clouded judgment caused him to seek out solutions from the darkness of evil forces and use their sorcery to serve his own selfish needs. With his lands falling victim to darkness, King Jovana’s pact with the malevolent Nightwitch cost everyone around him dearly, not least his own children. The once benevolent king and those who serve him, must fight a terrifying battle to end the reign of terror before all is lost forever!
