ABOUT THE AUTHOR: Annie Seaton lives near the beach on the mid-north coast of New South Wales. Her career and studies have spanned the education sector for most of her working life, including a Masters Degree in Education, and working as an academic research librarian, a high school principal and a university tutor until she took early retirement and fulfilled a lifelong dream of a full-time writing career. Since 2014 Annie has been voted Author of the Year (2014) and Best Established Author (2015 and 2017) in the AusRom Today.com Reader's Choice Awards. In 2018 Whitsunday Dawn was voted Book of the Year by AusRom readers, and also finalled in the ARRA Romantic Suspense book of the year awards.

Each winter, Annie and her husband leave the beach to roam the remote areas of Australia for story ideas and research. In 2016 they visited the Undara lava tubes. The Undara lava tubes stretch for 160 kilometres—indeed Undara is an Aboriginal word for ‘a long way'. Ancient roof collapses have formed a network of caves where plants and wildlife thrive in unique ecosystems. This fascinating geological marvel inspired Undara, and the story of Emlyn Rees, and the Carlyle family.
