The story is about:
... the dreams and visions of inexperienced virgins three sisters (tre sorelle: Angela, Trifona, and Gracijana), daughters of the Italian Crossi family whose father is the distinguished captain of the ancient and famous Boka Navy...
… the religious virgin Angela who marries a versatile Croat from Boka Kotorska...
... Angela's descendants tell her life story through their memories...
… the longings of Mary Magdalene in all the women of the world...
… the impregnable fortress of the City-State of Kotor in the Boka Kotorska fjord in South Dalmatia with its Catholic-oriented Destiny...
… heavenly spiritual beings, merciful archangels, and angels full of holiness, grace, mercy, and care for all who worship them...
… hospitality and kindness as a moral law that is a prerequisite for bliss and victory...
… the science that is false without a religious approach and foundation...
… the gardens of the Mediterranean and their arboretums adorned with the dendrological-botanical motto ARBOR VITAE, ARBOR MUNDI...
… a message in a bottle that - like human life - is interesting for reading but not sufficiently comprehensible to remember for a long time…
