It was published in eight-page installments in the America's Best Comics anthology Tom Strong's Terrific Tales, the first ten issues of which Adams penciled from 2002–2004.
For example, in the second installment, "Moth Women of the Myriad Moons", Jonni battles a swarm of creatures with greatly exaggerated female characteristics like her own.
Jonni's uncle came and went at his pleasure from the 20th century to the Crepusculum, a time billions of years in the future when the whole solar system teeters on the brink of collapse and several planets have already disintegrated in a maelstrom of asteroids.
Jonni encounters Jermaal Van Pavane, an anthropomorphic cheetah, who crossed from the pulp universe via a dimensional bridge in the attic.
Jermaal becomes her sidekick in the campy action, explaining that her uncle wished her to take up his mantle as a hero and protector of the Grand Array, the fantastic universe he lost his life defending.
