Petra Kronos has a simple, happy life. But it's never been ordinary. She has a pet tin spider who likes to hide in her hair and give her advice. And her brilliant father has been commissioned by the prince of Bohemia to build the world's finest astronomical clock. When the prince steals her father’s eyes to wear them as his own, Petra sets off for Prague to steal her father's eyes back. And that is only the beginning of this series brimming with magic and adventure that Publishers Weekly called a "heady mix of history and enchantment." Includes all three books in the series, The Cabinet of Wonders, The Celestial Globe, and The Jewel of the Kalderash.
