Former Sky Commander Breta gets more than he bargains for when he volunteers to investigate the build-up of troopers in the southern bay region, but this only serves to strengthen his resolve to coordinate a full-scale revolution in Australia. Members of KAL - the Kauri-Australia Line - prefer a more cautious approach: withdrawal of labour and transport strikes, leaving Breta fuming at their failure to seize the moment.The situation alters when villagers in the northern Brown Zone stage their own small insurrection, the Sky Lines Alliance is formed and Operation Unity begins.The final book in a gripping trilogy of a future dystopian Australia, The Sky Lines Alliance is a tale of bloody revolution tempered with acts of compassion as three groups join forces to overthrow the totalitarian Australian government and restore democracy. Pia and Kaire play key roles that challenge their principles and commitment, forcing them to accept that radical change cannot be achieved without recourse to the dark side.
