Rosebud is the 28th Proposed Serial in Spectral Shadows. It is preceded by Serial 27 - The Valley of the Tauran Bears and succeeded by Serial 29 - The Wild West Hero. It is currently not being worked on, meaning that the only available material is the summary on the Synopsis Page. Its namesake comes from the movie Citizen Kane.

The summary is as follows:

The Black Knight takes an interest in becoming Jon's nemesis and confounding his efforts on Taurus 5. Their confrontation eventually ends up in a duel at The Point Of Know Return, the loser to be forced through the gate from which no one has ever returned to tell what lies on the other side.

Jon loses the duel and is flung through the gate. And after a sense shattering psychedelic vision of universal creation he finds himself in the room of a reclusive paraplegic girl who explains that she is The Goddess, and that Jon is nothing more than one of her schizophrenic fantasies.

Jon then spends a good bit of time getting to know the handicapped girl and getting involved in her personal problems.
