The Sacrifice is a time travel romance/adventure that takes place in Melbourne, Australia, with multiple scenarios that alternate between 2017, the early 1900's, 1960, and 1975.

The tale begins in 2017 where two young ladies are sent back to Edwardian Melbourne, courtesy of a mysterious portal which is situated in a former punishment hole of the Kew Asylum, now situated below a residential unit.

The intrepid time travellers are Jessica Tomic, a famed investigative journalist and her assistant Zara Black, a karate expert.

Their task is to save the lives of two women. The first of these women is Vida Goldstein, the internationally renowned, first-wave feminist. The second is the assassinated beloved of the person who sends them back in time, an enigmatic old man known only as Mr. X, himself a time traveller from the past. He is aided by a beautiful, elderly woman named Ruth.

Unbeknown to Jessica and Zara, if their mission is successful and both ladies' lives are saved, the mysterious Mr. X will no longer exist in the future, an outcome he is earnestly praying for.

Due to remarkable circumstances, in which a playboy called Simon is transported to 1960 from Edwardian Melbourne, Zara and Jessica are faced with the dilemma of either returning back to 2018 or completing their lives in Edwardian Melbourne where they have found love, contentment, and families of their own.
