The ruthless Empress Amara of Kraeshia has taken the Mytican throne, and now uncertainty looms over the three kingdoms. Since Lucia unleashed the fire Kindred, wreaking havoc throughout the land, Myticans have been looking for someone—anyone—they can trust. They believe in Amara, not knowing her grand promises are built on lies.

In Paelsia, Magnus and Cleo reluctantly follow King Gaius to the home of his exiled mother, Selia. Selia is a powerful witch and claims she can help unlock the magic of the Kindred—if the visitors agree to her terms. When Jonas arrives from Kraeshia, he is shocked to find that his rebel army now includes his sworn enemies. Along with Nic, Felix, and the mysteriously resurrected Ashur, the contentious group agrees to cast aside old grudges—for now—and united against their common enemy: Amara.

Meanwhile, bearing the child of a Watcher and feared by all, Princess Lucia travels across Mytica to find her family. But time is running out. The impending storm signals the dark prophecy Timotheus warned her about. Her fate is written, and it includes none other than the rebel Jonas. When their paths collied, Jonas and Lucia must decide between blindly following their destiny or fighting for their own free will.

The battle for power culminates at the Paelsian palace, where Amara resides. Rain pours. Blood spills. And soon all will discover that the darkest magic comes at an even darker price.
