The Pearl Sister No.4 (2017) by Lucinda Riley

CeCe D'Aplièse has never felt she fitted in anywhere. Following the death of her father, the elusive billionaire Pa Salt – so-called by the six daughters he adopted from around the globe and named after the Seven Sisters star cluster – she finds herself at breaking point.

In desperation, CeCe decides to follow the clues to her past left to her by her father: a black-and-white photograph from 1906 and the name of a female pioneer, Kitty McBride, the daughter of a clergyman who left her rigid life in Scotland to forge a new path in Australia.

On her way to Sydney, CeCe visits the stunning beaches of Krabi, Thailand. There she meets the mysterious Ace, a man as lonely as she is, a man with a secret to hide . . .

When CeCe finally reaches the searing heat of the Red Centre of Australia, something deep within her awakens. Could this wild, vast continent offer CeCe something she never thought possible: a sense of belonging, and a home?
