My new characters, Siena Biancchi, her twin sister Renata, and Siena's best friend Xander Chase (no relation to Annabeth Chase) embark on an adventure across the globe. They've been outcasted. Explosions happen whenever they're around. And worst of all, these weird monster things keep trying to kill them. Siena's got it worst. Not only is she strange, but her appearance makes everyone whisper behind their backs. Her hair color has been naturally highlighted. She was born with a brand of the sun on her arm, and occasionally, an invisible force cuts symbols into her skin at night. But Xander, her bff, helped her through everything, and Siena's sister Renata is always there for her. What will become of them? How will these youngsters survive on their own? And what happens when they meet the Seven? (Siena and Renata are nine when story begins. Xander is ten when story begins)
