Colder Than Ice — Jennifer Smith

Kristine's life has never been what most people would describe as normal, but when she begins at a new school with her best friend things get even weirder. Everything she though she had known is turned up side down, people she loves are people she can no longer trust and those that she put walls up against are tearing them down. Aiden gets under her skin and shows her a world she never knew existed. In the end, Kris is forced to make a decision she is not prepared for and is being driven purely by betrayal.
With everything she knew ripped away from her, she turns colder than ice.
