The Clock Diamond

It's the year 2284, and three normal teenage girls are living a normal life in the cities of South Carolina when disaster strikes. However, with luck by their side, they beat the odds and manage to escape.
That is, all except one.
16-year-old Coraline Ramirez is stranded on an Earth that is about to explode by her two friends, believing she was betrayed. When a mysterious man appears in front of her and tells her that he will save her from her impending fate if she captures her friends and turns them over to him, she reluctantly agrees, her mind still awash with a mixture of confusion and fury. Meanwhile, her two friends are stranded on a barren planet with supplies running out. But when they get a strange message telling them how to turn back time, their mission to stay alive becomes a mission to go back to the past and save the human race.
But unbeknownst to them, they may just be tangled up in this whole mess more than they think they are...
