Two lives, one hope. . . .All Sarah Lind's dreams now seem within her reach: not only is she welcomed back to the Six Realms as the Queen of Ice, she is now days from her marriage to their dragon-shifter King of Flame, and, united by their powerful bond, Sarah and Ben have so far thwarted the Devourer's attempts to ruin the Realms' recovery from its invasion.Yet there is still one more dream for her to discover. However new and growing, that dream proves to be one of the most potent, and, according to the Tree of Ice, the key to saving the Realms from the Devourer once and for all. For though a King is dangerous, a Queen is more powerful. Because she, like a Tree Herself. . . can become a mother.All Koriben Sunfilled's hopes now rest on the promise the Tree of Flame gave him that if he did as She commanded, Sarah—the one person he cannot live without—would survive the darkness coming for her.Yet his Tree's command tests him to his very core, because it echoes his parents' own sacrifice to give him life, the cycle he had once vowed would end with him. But after losing so much, Ben will now do anything to save Sarah. Anything. Even . . . become a father.As desperately as they want to live and save their Realms, Sarah and Ben resolve to have a child only for the right reasons. Yet even as they wait to be sure of rightness of that course, their time is once again running out, for the Devourer will not tolerate the growing threat the Monarchs of Ice and Flame pose. Sensing in them the culmination of millennia of Tree preparations for its final defeat, the Devourer has determined they must die—and it knows just how to lure the Queen of Ice into the open. The Devourer will invade once again, this time coming for the fading Tree of Ice, whom Sarah is sworn to protect. This time . . .. . . it is coming for Earth.
