Dory Winthrop has been the designated Chosen One by ancient Prophesy for over three centuries, but she's never been comfortable with her calling as an Immortal savior. Now, just when she's struggling with her fate more than ever before, she and her team are again tasked with protecting the world from peril. They must find the key to avert a threat that could change the world in inconceivable ways and upend history. With the assignment coming from an astonishing source, Dory must find a way to be the shield for the world that she was meant to be... and finally make peace with her destiny.

With a few more years as an Immortal under his belt, unlike Dory, Kaden Crenshaw, has embraced his role as Chosen Warrior. By Dory's side, he's done things he could never have imagined, seen things that even now he can't explain. Just when he thinks he's got a handle on this new Immortal life he's been shown, something new challenges his very core beliefs. This latest mission is no exception, to say the least. However, for him, it's about trust and faith, and he will not falter. He'll support the love of his life and lead the team to the mission's conclusion because failure is not an option.
