Cullen wrote two novels;
Home (1802), and
Mornton (1814). The authors of the
Biographical Dictionary of Scottish Women describes her work as suggesting a "reforming outlook and a committed interest in the condition of women" with
Home a "didactic and provocative attack on the existing laws of inheritance, influenced by her own awareness of women's financial vulnerability".
Mornton is notable for an extensive debate on the rights of animals, written in the wake of the failure of
Lord Thomas Erskine's animal cruelty bill in the House of Lords. ==Bibliography==
