An ancient prophecy. A destiny of flame. A war to end two worlds . . . A dark prophecy binds Cora's fate to the fae realm--a world that would have been her doom if she hadn't escaped with her life. Now she's determined to put destiny behind her and focus on her world, her kingdom, and her much-anticipated wedding. But when dragons emerge from the veil between worlds, threatening her land with deadly flame, she must return to the fae and make allies of those who had once condemned her to die. Yet dragons and fae are the least of her foes. Her greatest enemy marches on her kingdom, and he won't stop until he controls fae magic. Fate and fire collide, but Cora isn't alone. She, Teryn, Mareleau, and Larylis each have a role to play in protecting two realms from an ancient king who can walk between worlds. When the dust clears and the ashes settle, will the embers of hope remain?
