A Pennyworth of Sunshine by Anna Jacobs
Keara Michaels doesn't want to leave her family in Ireland, but fate sends her first to Lancashire, then across the sea to Australia, pregnant and penniless. And Theo Mullane, the man who loves her, is married, with an ailing baby son, so cannot follow her as he longs to. Mark Gibson leaves Lancashire to avoid marriage. But gold prospecting is a dangerous pursuit, and when his gentle young wife dies in childbirth, his father-in-law kidnaps the baby. So Mark runs away again, this time to Western Australia, where he employs Keara in his country inn. But danger threatens them all, even in the bush, as Keara searches for her lost sisters, Theo comes looking for the woman he loves, and Mark at last confronts his past.
