In the aftermath of Dauntless, Kacey Alexander embarks on her new life as a Sentenial battling the forces of darkness. Joined by Dark Fae, Aiden, and newcomer mage, Marissa, Kacey and her team discover the dreaded blood mage Morrigan is back in town and seeks to destroy humanity and build a world controlled by mages.

As Kacey navigates her complicated relationship with Aiden, and with feelings blossoming for Marissa, Kacey finds herself embroiled in a battle to control her heart, but there are bigger concerns. As Morrigan’s plan becomes clear, their only hope lies in TITAN, a cutting-edge suit engineered to resist even the deadliest magic.

With the help of an eccentric billionaire, Kacey gathers a new team to take on fae lords, shapeshifters, and Morrigan’s dark forces in a battle that will decide the future of humanity.

The battle for the future, and her heart, has begun.
