When Hawk and Zach Callahan arrive to start a new life in the wilds of Alaska they find the first challenge is just getting to the small town of Salmon Run. But, Alaska has more in store for them. Such as a massive aurora, the Solar Express train shutting down the middle of nowhere... and then there is the alien spaceship hidden beneath the ice and snow...

Avery Fallyn might be hearing things. At least that's what fellow werecat Xander Hawkes thinks when she tells him about the strange howls and snarls that she hears from the woods at the back of her house. He's sure it's just a side-effect of the medication she's taking, but Avery thinks otherwise. Desperate to prove that she's not crazy, Avery decides to investigate behind Xander's back, only to find out that Crescent Falls is more dangerous than the two of them ever imagined.
