Sunset Eyes and Crystal Tears

She is fire and ice. Rain and sunshine. Fierce and calm. She's the redemption the world needs and the one thing that can tear apart the very fabric of it. She is death incarnate with the face of an angel warrior. She is Twyll Merrick- The Crystal Heir. Twyll has a fire in her that can burn and burn untill it destroys. She is the last Crystal Heir. The only one who can wield the Core Crystals. But there is one tiny problem. She doesn't know that she is the heir that never was, and when she is pulled into the pulsing world of the CrystWorld after the jarring loss of her aunt - her only family - she turns to a boy with sunset eyes and his group of friends who are determined to help her - whether she wants it or not.
