"Two children from a forgotten land, ancestors of the Island of Ohm Totem, one being of the night walkers and the other of the sacred heart, will purify the energies, bring back the old ways, and unite the PureLights once again, putting an end to the coming Shiver." ~ Windstorm Prophecy Zoey and Coda are like everyone else in their small town of Gladstone, but that's about to change - forever. Zoey has a dream, one that feels far more real than it should. A strange wolf with a beautiful violet crystal embedded in his forehead visits her. "Please help us," the wolf implores with sad eyes. "Remember, Zoey, who you truly are." Zoey wakes up, dismissing it as a silly dream. However, she soon realizes that it was far more real than she could've ever imagined. Coda is Zoey's older brother. Like many boys his age, he has a craving for adventure and a loathing for his younger sister. He can't stand it that she constantly gets in his way, joining in on all his fun, and ruining it in the process. The worst, according to Coda, is that Zoey gets all the attention from their parents. A big drag in his mind. Then destiny arrives, one that Zoey and Coda must face together - if they want to survive. Together, they journey to a place deep in the Cornell Forest, beyond the Snow Tree, through a patch of blackberry bushes concealing a secret portal that leads them to an ancient world called Ohm Totem - to the place of the PureLights, the race beckoning for their help. There, Zoey and Coda discover something so unique, so magical, and so sacred within themselves, that even those who called for them could not have known how powerful these two children really are. Caught between an age old war and finding their way back home, Zoey and Coda go on an amazing adventure, taking them beyond the veils of everything they once knew, and into the terrifying grasp of the unknown.

Zoey has been taken by the all-powerful, malevolent Crepus Dim and Coda will do anything within his power to save her. He and his friends set off on a mission to rescue his sister where Coda soon finds himself in the Dim Lands, a place much different and more dangerous than the place he just left. There, Coda comes face to face with himself, discovering the truth of his true identity and why he has returned to Ohm Totem. Soon, he is confronted with two choices—to face his fears and understand that the impossible may actually be true, or to run from the truth knowing he has a much better chance of survival if he does. Zoey is caught in Crepus Dim's deathly energy grip. Can Crepus' powerful magic and manipulations prevent her rescue? Nevertheless, it may be too late. The prophesied "Shiver" is upon them all, bringing with it a long hidden creature that can destroy everything within it's path—even Nova, the wisest and most talented of all the seers.

Zoey is on the run with malicious Dims in hot pursuit. They are determined to stop her from reaching her destination—the great Pyramid of Ohm. Attached to Zoey’s leg is the sacred scroll of the PureLight Order and the golden key, hidden from view by a powerful spell. She must deliver these to complete her mission and to help save the PureLights. What Zoey doesn’t know is that she also holds the secret to something even more valuable—something the Dims will gladly sacrifice their own lives to destroy. Coda has already arrived at the Pyramid of Ohm, but he is trapped inside one of its chambers by a Dim spy. Coda knows he has only one day to escape before the chamber burns him alive. The VioletLights—the sages of the PureLights—must help their friends defend themselves in the final battle against the evil clutches of Crepus Dim and his army. Their last chance of hope is to convince the Thunderbirds, an ancient race of giant birds, to help them. Will the Thunderbirds turn the PureLights away and watch them crumble under Crepus' fatal rule? Get ready for the last book of the PureLights trilogy. It's a white-knuckle rush to the end.
