Wren Calder has always been good at staying invisible: at home, at school, even in the crowded hallways where louder voices take up all the space. But on a quiet afternoon in the school library, she stumbles upon something she was never meant to see: a brass lantern glowing faintly in the dustiest corner of the shelves.
When she lifts it, the shelves shift to reveal a hidden staircase… and a doorway into a place beyond anything she’s imagined. Talking books, rope bridges of paper cranes, and a man in a green coat who seems to know her name and insists she’s here for a reason.
One question echoes in Wren’s mind: What’s a spark… and could she really have one?
