Beyond the sunset - Anna Jacobs

In the untamed outback of Western Australia, the Blake sisters are together again despite what seemed like unsurmountable odds.
For Cassandra - reunited again with the man she loves - the Swan River Colony is a refuge that seems like a miracle after her ordeals. And two of her sisters have fallen in love with their new way of life. But then a messenger arrives from faraway England, and it is the fourth sister, Pandora, who jumps at the chance to make her way back to the Lancashire moors that she misses so badly.
The way home, though, will be even harder than the voyage to Australia. The only ship that can take her and her new protector back to England lies many days' journey away, across country that would daunt even a hardened explorer.
And when she reaches Outham, a devious, dangerous enemy will do anything to prevent her from taking charge of her family's inheritance . . .
