Deborah Challinor Behind the Sun.
The story of four convict women coming the Australia from the UK in 1830.
Very enjoyable book number 1 in a series of three
Number 2 is Girl of Shadows
Number 3 is The silk Thief
Number 4 is a A Tattooed Heart.
I have personally read all of Deborah Challinor books and wish there were more
