Lord Keverin is desperate to save his people and the kingdom he serves from the sorcerers of the Protectorate. Desperate times call for desperate measures. A spell is cast to bring a champion to Lord Keverin's aid, but something goes wrong and a Julia Morton suddenly finds herself stranded on an alien world with no friends and no way home. The God Decrees is a fine beginning to this fantasy series.

A year on from Julia Morton’s arrival at Fortress Athione, an uneasy truce is being maintained between Deva and her enemies, but the Protectorate never rests. Believing himself destined to rule, Lord Mortain unleashes General Navarien upon the north in an effort to bypass Julia’s guardianship of Deva’s western borders. Meanwhile, having rallied the scattered forces of a dead traitor behind him, Rowton of Ascol moves ahead with his plans by murdering the King. With the King dead, and the lords vying for his throne, Julia tries to ensure the right man is chosen for the job. When things go wrong, she resorts to force, but sorcerers won’t be pushed, and soon the lightning bolts fly again over Deva.

Julia Morton, sorceress of Athione, has been saved from her abductors at Kerrion's insistence by warriors from the Night Wind Clan. Grateful to be alive, but not yet well from her ordeal, Julia swears to repay her debt by destroying Kerrion's enemies once and for all.

The war rages on and General Navarien is advancing into Deva despite all the clans and Julia can do. King Gylaren must march north to oppose the invasion, but it takes time to muster the army, and there is no time. With war in the north, and Japura now allied with Tindebrai, Gylaren sends his son and heir on a desperate mission to seek aid, but before he can march to join Julia, the unthinkable occurs and Fortress Malcor falls to the Hasian invaders. Lord Jihan retreats to Waldenvale and Julia leads the remnants of the clans to ally with him, but Navarien has plans of his own and is not satisfied with controlling Deva's greatest fortress. Despite Julia's magic, despite the awsome fighting skills of the clan warriors, Jihan knows his defeat is inevitable. The best he can do is slow the Hasians down with the blood of his men, hoping by some miracle the King can reach him before its too late.
