Frozen Fire

Telepathic seventeen-year-old Denefe Xia and her twin sister, Kaleen, may not have had any other family, but they always had each other. In a natural disaster, Denefe is sucked into the past by a wormhole where she discovers she has a hidden triplet, Torenz, who was raised by parents she thought had died when she was a child. Through a telepathic connection with the future, she learns that her only way home is degrading and will soon trap her in the past forever if she doesn't take action. The trouble is, Torenz won't let her near it.
