The dark unknown beckons. Rune Jenkins has a long-standing infatuation with anything from the supernatural world, and she's trying to hide it. If she doesn't, she angers her reckless twin brother Ryker, and starts feeling like her own sanity is slipping. But the closer she gets to Grey Malteer – an old friend who waves his fascination with fantasy like a flag – the harder it becomes to stifle her own interest. The supernatural suddenly invades their reality when other-worldly creatures come hunting for the three college students. With help from a mysterious savior Rune and Grey escape, but must follow Ryker's abductors into an alternate dimension, Eon, and discover their true identities. They are Venators, descendants of genetically enhanced protectors and sentries between Eon and Earth. In this world of fae, vampires, werewolves, and wizards, power is abundant and always in flux. Ryker is missing, and Rune and Grey are being set up as pawns in a very dangerous game. The three must find their way through – and out of – Eon, before it consumes them.
It has been mere days in the world of Eon, where Rune Jenkins, her twin brother Ryker, and their friend Grey have been trapped, fighting for their lives. After discovering the truth of their ancestry, the three are far from home, and far from anything resembling their mundane lives of the past.While Ryker is still held captive by the eerily beautiful Zio and her goblins, Grey fall into the clutches of Feena, the Fae queen. She begins to drain his soul bit by bit to feed her dark underground garden, and Grey has no hope of escaping on his own.It is now up to Rune to save Grey, as his precious time slips away inexorably. But the Council has denied her permission to embark on a rescue mission, until she can harness her Venator gifts and prove herself capable of venturing into the Fae queen's territory. As Rune discovers that promises in Eon are forged with life-or-death consequences, she realizes that she must act quickly, or else be swallowed – and Grey along with her – by the dangers of Eon.
