New York Times and USA Today bestselling authors Mercedes Lackey and James Mallory teamed up to write The Obsidian Trilogy, set in a wondrous world filled with magical beings, competing magic systems, and a titanic struggle between good and evil.
That world proved so popular with the creators and readers alike that Lackey and Mallory have returned to it with The Phoenix Unchained, Book One of The Enduring Flame,

"Joy must uncover a deadly conspiracy at the heart of Apex City--and lead her fellow Hunters to victory in the final confrontation with the dangerous Othersiders"--

"A teenage girl leaves home to join the legendary Hunters, who protect the people from the terrifying monsters that have overrun their world"--

The human race teams up with hated magical beings in order to survive a war against Demon forces, while Knight-Mage Kellen and his band of unlikely companions head a vast Light army in a battle against Darkness.

In The Phoenix Endangered, second in The Enduring Flame, Tiercel, a budding High Mage, and Harrier, a reluctant Knight-Mage, develop greater power--and learn of the evils of war when they see the devastation caused by the fanatical armies of the Wild Mage Bisochim. The desert tribespeople led by young Shaiara flee Bisochim's evil, seeking a legendary oasis deep in the desert--a refuge that may hold the key to stopping Bisochim and preserving the Balance...

As Vieliessar confronts the first waves of the forces of Darkness, her destined bondmate, Runacar, leads a rag-tag group to war. For centuries, the Elves have hunted the Otherfolk, minotaurs, gryphons, dryads, and more, considering them beasts. But they have a complex society, Runacar discovers, and though he is an Elf, takes it as his mission to help them reclaim their lands from his former friends and allies.
