chapter one
the night seth found mercy
in which a firefly picks a door, and a plain hero looks up at exactly the wrong (right) time
The sky over Ooo is doing the thing again.
Up in the Umbrella Observatory — a crooked wooden tower bolted to the top of the treehouse, held together by nails, hope, and one very stubborn tarp — Seth adjusts the brass telescope for the ninth time tonight. The sky is bruise-purple bleeding into candy orange, and the striped mountains in the distance glow like somebody left the oven on. He notes it, quietly, in the little grid-paper notebook he keeps clipped to the railing. sunset, again. still doing its whole thing. still pretty.
"yeah," Seth says, to nobody. "the sky is doing the thing again."
He is a very average shape against a very unaverage sky. Plain white tee. Dark jeans. White shoes scuffed at the toe. No tattoos. No rings. Thin rectangular glasses catching two tiny sunsets, one in each lens. He is the sort of person the eye slides right off of, which is exactly the sort of person a curse cannot find. Class: Plain Hero. Null-class. The universe forgets to aim at him. He kind of likes it that way.
Down at the roots of the tree, the little cottage window flickers with candlelight. Somewhere in Ooo, a bell hums — not rings, hums — low and warm and wrong, like a lullaby sung under water.
Marceline the Cat is awake.
She is stretched across a leaning basalt tombstone that reads HERE LIES A GOOD MOUSE, 1987, and her single visible fang catches the last of the light. A firefly drifts past her nose. Not a normal firefly. This one glows pink, which in Ooo means it has opinions. Marceline's tail twitches. The bell on her red collar hums a full step higher. She launches.
The firefly zips up the tree. Marceline follows — paws on bark, paws on windowsill, paws on the little wooden ladder that only cats and drunks know how to climb. Up, up, up, past the kitchen, past the loft, past the sign that says OBSERVATORY: PLEASE KNOCK (SETH IS SHY).
And down in the Rose Cemetery Kingdom, someone notices her cat is gone.
Mercy, the Rose Necromancer Queen, is barefoot in the graveyard when she feels the tug on the little thread of magic she keeps tied to Marceline's collar. She looks up. Orange-to-pink ombre hair catches the sunset like it was made for the sunset. Blue eyes. Heavy eyeliner smudged just enough to look on purpose. Septum ring. Lip ring. Spiderwebs and bats and small careful flowers laddering down both arms. On her chest, over her heart, in tidy old-timey letters: PRETTY GIRLS MAKE GRAVES.
She sighs. She loves that cat more than she loves most kingdoms.
"okay, little witch," she says, gathering the hem of her all-black bodycon like a queen gathering a battle standard. "let's go get you."
Chunky platform boots. Fishnets. Gold-chain shoulder bag with a tiny skull charm swinging like a pendulum. The skull is grinning. Mercy is not, quite, but her mouth is thinking about it.
She follows the bell-hum across the fields of night-blooming roses, over the little bridge where the frogs go quiet when she passes, up the hill, up the tree, up the ladder, up — until she is standing at the top of a crooked wooden tower she has never seen before, one hand on the door that says PLEASE KNOCK (SETH IS SHY).
The door is already open. The pink firefly is orbiting a brass telescope. Marceline is sitting on a plain boy's shoulder like she has always lived there.
The plain boy turns around.
He does not say whoa. He does not say my liege. He does not do the thing boys do when a Necromancer Queen shows up in their doorway looking like the last page of a very good book.
Seth just pushes his glasses up his nose, glances at Marceline, glances at Mercy, glances at the sky one more time to make sure it is still doing the thing — and it is, oh glob, it really is, pinker now, softer, aimed — and he says, very quietly, like he is telling her a secret the observatory already knows:
"yeah. the sky is doing the thing again."
Mercy, the Rose Necromancer Queen, in the doorway of a treehouse she was never supposed to find, tips her head. The skull charm on her bag swings once. Twice. Stops.
She smiles. Just a little. Just enough.
"yeah," she says. "it kinda is."
and downstairs, in a cottage neither of them has noticed yet, a kettle starts to sing.
