The Cabinet of Wonders

I have just finished The Cabinet of Wonders by Marie Rutkoski. It is about a girl named Petra Kronos, she lives a quiet life with her friend Astrophil, a tin spider who likes to hide in her hair. Her father had been asked to make the worlds  finest clock for the prince of Bohemia. When he returns he is blind. Petra decides to go to Prague, where the prince lives, to get her father's eyes back. Her plan is changed when she joins with Neel a boy from the city who can help her pick locks and get her fathers eyes without the prince knowing.
