As an air witch and meteorologist, Aura Burton has dedicated her life to keeping others safe. As one of the Elementa, she carries an even greater burden, one that often means putting herself in danger to protect others.

Killian O’Rourke has secrets. More than one, in fact. He escaped the future his family had planned for him and has been happily living life on his own terms—until the past he left behind comes knocking.

When witches begin disappearing and strange weather phenomena plague the small coastal town of Rock Cove, Aura is uniquely qualified to investigate. With Killian at her side and the bonds of her coven growing stronger, she may have a chance to uncover the truth.

As fragments of an ancient prophecy begin to unfold, Aura and her coven face a terrifying truth: they are the last line of defense against the Harbinger, a force capable of destroying everything.

And if they can’t stop it, the world will pay the price.
