Frostbite [Destroyers Series, Book Four]

SOPHIA THOUGHT THAT A SIMPLE CASE OF POSSESSION WAS BAD ENOUGH...
For the past few years, Sophia has been plagued by the Other, a mysterious, evil presence within her. And whenever it's angry, it lashes out...by freezing everyone and everything nearby.
When Sophia's boyfriend betrays her, and she flees, she's discovered by Cordelia, the new storm goddess now hunting for soldiers to war against humanity.
And the Other makes its intentions clear: it will join Cordelia, bringing horror and death to the world. To stop it, Sophia must turn to a new group of friends: Janelle, Gareth, Leslie, Kenna, and Paul. But even they can't keep the world safe, and Cordelia has a few tricks up her sleeve.
Frostbite is the fourth book of the Destroyers Series, a young adult paranormal and fantasy series originally written in 2010.
