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.
