Publisher's summary
During the events of Doctor Who: Ravenous 2, Liv Chenka left the Doctor and the TARDIS behind. Just for one year. A year during which she would live on Kaldor, and get to know her sister Tula all over again.

But Kaldor is going through a period of tumultuous change. Technology is changing at an advanced rate - the robots are evolving, artificial intelligence is adapting, and with these changes so politics is altering too. Dangerously.

Can Liv and Tula make a difference during the most turbulent time in the world's history?
