- Freud Was Right: The Pocket edition of The Serpent sports a buffet of phallic symbols on the cover, thus accurately underscoring the novel's sadomasochistic elements.
- Genius Bonus: One member of the Fantasywithbite LiveJournal community described the world-building in this series as "catastrophic," but this defect is the result of Gaskell's reliance on the reader's knowledge of unorthodox prehistory. The sources in the first two books' bibliography can point the confused reader in the right direction. note
- Iron Woobie: Cija can endure anything: kidnapping, rape, war, arranged marriage....
- MST3K Mantra: Abandon hope, all ye who enter this series expecting a storyline based on accurate prehistory.
- Squick: Be prepared for rape and bestiality if you decide to read these novels.
