A work in progress. Subject to revision
A work in progress. Subject to revision was a never-retitled fanfic by Chris Tucker.
Inspired by the joke about "uranium in the drinking water" in "Esteemsters", the fanfic has Daria diagnosed with aggressive cancer and leukemia seven months before graduating; Daria goes through a sixth-month "Season of Hell" to beat the cancer into remission, before returning to Lawndale High.
"A work in progress" story goes non-linear a lot after the second chapter, to fill out the details of what happened.
The fanfic spawned over a dozen other stories in the same continuity. Several backstory elements are established here which carry on, such as establishing Aunt Amy works for the FBI; and Daria & Quinn are actually Helen's nieces by way of an extra sister, Elizabeth, and they'd suffered extreme neglect and abuse before being adopted by the Morgendorffers.
