There is a world above and a world below; and Aspen Matthews struggles to walk a line between the two. Beneath the radar of the humans on the surface, an ancient race of powerful beings called the BLUE thrive along the depths of the ocean floor. Aspen was born among them, but an adoptive human father raised her on the surface world. In the past, Aspen has sided with the humans as she fought to stop a BLUE dissident named Killian from his destructive plot for domination. With the full extent of her incredible powers unleashed, Aspen found herself back in the water, this time fighting alongside Cannon, Kiani, her brother Finn, and the rest of the BLUE against an invading human army. Leading the attack on the secret world below was Admiral Maylander, a man who sees the BLUE as clear and present dangers to human kind’s survival.
