At 1:19 a.m., a star beside Saturn goes out. Maya is sure Saturn's ring is a solid hoop sliding over it, and the old observatory key can take her there to prove it. But nothing out in the ring looks like it does from home, and the lantern holds oil for only one night.
Sky Keepers
Ages 10–12Sky Keepers is a series of illustrated adventures for readers aged ten to twelve about space as it really is. Cousins Maya and Leo, with a clockwork owl whose star chart stopped in 1889, step through an old observatory door to real places in the solar system and beyond. Each book delivers one astronomy topic through a story with real stakes, and shows how astronomers found out what the owl never knew.
