Isabel Clarke has spent her life believing she is an ordinary Somerset farmer’s daughter, content with horses, village life, and the quiet certainty of knowing where she belongs. But when a series of strange events begins to unravel the truth surrounding her birth, Isabel is drawn into a world of aristocratic power, hidden loyalties, and secrets buried since the years before the Second World War. Far away in the Australian outback, Barbara Frazer has always felt like an outsider. Fiercely independent and determined to escape the control of her adoptive parents, she has no idea that her life is bound to Isabel’s by a mystery neither of them yet understands. As the two young women move unknowingly towards one another, powerful figures within government and society watch from the shadows, desperate to keep the past hidden. At the centre of it all lies a devastating secret linked to one of Britain’s most prominent families. Set between the rolling hills of Somerset and the vast landscapes of Australia, Charlotte’s Legacy is an emotionally rich historical mystery about love, identity, family, and the extraordinary strength of two sisters separated at birth.
