about the size of Lizaâs palm. They looked like butterflies, except that they had the long, pointed beaks of hummingbirds, and they seemed to be made out of darkness and air.
There was a rustling, as thousands of quiet voices spoke in unison.
âRelease the rat and the human child,â the nocturni said, and their voices sounded like dry leaves tumbling over one another.
âYou heard them,â the judge croaked out. âRelease the defendants at once.â
Liza found herself released. Instantly the nids began to withdraw. As they backed slowly and cautiously out of the court, they tittered anxiously, scanning the air above their heads and muttering various apologies at the floating, flitting shapes.
âA mistake! A mistake! Happens to the best of us.â
âNo intention to offend â¦â
âA harmless little prank â¦â
âVery sorry, of course, wonât happen again â¦â
Soon Liza and Mirabella were left alone with the swirling black nocturni.
âWell,â Mirabella sniffed. âWell.â She patted her wig, parts of which had become hopelessly tangled. âI hope youâre happy. I told you to stay away from the nids. And now theyâve taken my purse.... If it hadnât been for the nocturni â¦â
âThe what?â Liza turned a full circle, stunned, all the while keeping her eyes on the drifting shapes above their heads, like a dark snow.
Mirabella muttered something that sounded to Liza like useless and humans and heads as empty as a beggarâs purse . At a normal volume, the rat said, âThe nocturni.â She shot another reproachful glance over her shoulder at Liza. âLucky they decided to speak up, or weâd no doubt be rotting to a pulp in the dungeons by now! Like forgotten bananas. Like turned cheese!â
âAre theyâare they dangerous?â Liza swallowed hard, thinking of the fearful way the nids had fled from them.
Mirabella dropped her voice to a whisper. â Very bad luck to displease the dream-bringers,â she murmured. â Very bad luck. I once knew a badger ⦠oh, but we wonât speak of him. Terrible, terrible. Spends his days counting socks at the troglod market ⦠convinced that the nocturni are sending messages to him through the color patterns â¦â
âDream-bringers â¦â Liza repeated. She didnât know exactly what Mirabella meant, but she liked the sound of it. âThere are so many of them.â
âOne for every person in the world,â the rat replied.
âNo.â This stopped Liza short. âItâs not possible.â
The rat whirled around, clearly growing impatient. âOf course itâs possible,â Mirabella said. âItâs necessary . You didnât think the nocturni would share, did you? There is a nocturna for every single person in the world! And each night the nocturni sip dreams from the River of Knowledge, and fly out into the world, and deliver them to their humans.â
âSo â¦â Liza struggled to understand what Mirabella had just said. âSo I have a nocturna of my own?â
âYou, the bus driver, the grocery store clerk ⦠The nocturni mate for eternity. Even after you dieââthe ratâs voice dropped to a hushââyour nocturna will never take another human, not for all the length of time in the universe and beyond. Your nocturna is wedded to your soul. Some even sayââthe rat paused again, chewing on her lower lip with her pointed front teeth, and coating them with lipstick in the processââthat it is the nocturni who carry souls into the Shadow World when we die, where they will watch over them and keep them safe forever. Some say that is nocturniâs ultimate purpose.â
Liza shivered. The cavern was cold, and full of shifting light. The underworld, she thought, was strange and beautiful and frightening, like the
