'An exciting e-only prequel novella to JOURNEY BY NIGHT. Tatsania's Gift is set on a dystopian Earth in the 24th century where there's no clean water, little food and life is a brutal battle against either the armed forces of ASSISt or other people desperate to survive. Six-year-old Kali is forced to fight for her life when her mother is dragged away by ASSISt and two cruel 'aunties' turn up to take care of her. But her mother has left her something precious - another girl, Nell, who no one else is able to see thanks to her mother's powers as a witch. Together, Nell and Kali, find ways to cope with the hard life the aunties force them into. They discover their own magical powers and join an underground movement where they learn the skills they will need to battle ASSISt.'
