For thousands of years the Elementals have chosen people to be their vessels as they help control the natural world and protect the people in it. Dante, Elijah, Stephen, and Christian are the latest generation of vessels. Stephen and Christian are destined to be together as Wind and Earth; Dante and Elijah as Water and Fire.

Then Elijah dies abruptly, tearing Dante apart.

Fire is reborn in Nicholai, and destined to be Dante's new mate—but Dante doesn't want someone new, and Nicholai is far too young to understand his new role and all his future will hold. As the years pass and Nicholai grows, Dante's constant refusals harden Nicholai against their bond, straining the relationship between all the vessels.

But if they're going to protect the world and ensure a future—for themselves and everyone else—they'll have to find a way to get beyond their pasts and let old wounds heal.
