My character will be a local who left to attend university and is (reluctantly) returning through her University of Miami marine biology program. She'll be a daughter of one of the local Big Deal families, but a black sheep and a troublemaker. Social hurricane, self sabotage, staying out all night type of gal. Stoked to hear these other ideas.
A wreck researcher being on-island at the same time as this university research program will be a hoot.
