Dragon's Shadow - Allison Morse

Royal twins ripped apart at birth become reluctant champions of good and evil. Kylie, a teenage science geek, has no faith in people. Instead, she relies on what she trusts the most, the facts—what she can see, touch, and hear but never feel. With enough pain to deal with in her own world, she is thrust into another—a kingdom at war whose strange inhabitants fear one thing the most—the return of the dragon. All of this is illogical to Kylie, but even more so, when she discovers she belongs there. Her brother, Prince Jarlon, journeys to kill the dragon who has laid waste to his kingdom. His only hope for destroying the beast is help from his sister, whom he has never met. Will their paths cross before the beast’s malevolence infects Kylie and turns her into his creature or will Jarlon have to destroy her, too?
