Sky 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.

But nothing out in the ring is what it looks like from home, and the lantern only holds one night of oil.
