In a Victorian era ruled by a ruthless steam baron council, mechanical power is the real monarch, and sorcery the demon enemy of the empire. Evelina has secretly mastered a coveted weapon - magic that can run machines. Should she trust the handsome, clever rake who speeds her breath, or the dashing trick rider who would dare anything she would ask?

    Now Mom and Dad are moving the family from Brooklyn to Maine hoping that it will mean a  whole new start for Lucca and Siena. She soon realizes that their wonderful old house on the beach holds secrets. When Siena writes in her diary with an old pen she found in her closet, the pen writes its own story, of Sarah and Joshua, a brother and sister who lived in the same house during World War II. As the two stories unfold, amazing parallels begin to appear, and Siena senses that Sarah and Joshua's story might contain the key to unlocking Lucca's voice.
