The author brings a message about building a house and a family and bringing forth new life. She does so by selectively using references from the Bible, rabbinic teachings, second temple literature, ANE writings, and modern scholars. This is interspersed with fictional vignettes.
An example of what I mean by selectively is her identification of the Tree of Life as God's Wisdom and the Tree of Knowledge as folly. Compare that to 1 Enoch which she sometimes refers to.
3...the tree of knowledge, whose holy fruit they eat and know great wisdom.
4...'This is the tree of wisdom, of which thy father old (in years) and thy aged mother, who were before thee, have eaten, and they learnt wisdom and their eyes were opened, and they knew that they were naked and they were driven out of the garden.' Book Of Enoch, ch XXXII (cf. Sirach 19:19)
This would seem to square better with Paul's teaching about the Law (Rom 5:12-13, 6:21-23).
The book focuses on events and characters instead of moral and legal teachings. She believes that Creation is built upon the union of male and female elements, as in the Enuma Elish.
