Heartlines (2016) is an adoption story with a difference, the difference being that it is written by adoptee Susannah McFarlane and her birth mother Robin Leuba.

In 1965, Robin travelled from Perth to Melbourne to give birth to her child. After 10 days, she returned to Perth and the baby, named Susannah, was adopted by a loving family.

In 1989, Robin tried to contact Susannah. It takes until 2014, however, before Susannah is willing to correspond with Robin.

Heartlines is the story of their reunion.
