They were born together and they will die together. One strong Alpha twin and one mutated Omega; the only thing they share is the moment of their death. The Omegas live in segregation, cast out by their families as soon as their mutation becomes clear. Forced to live apart, they are ruthlessly oppressed by their Alpha counterparts. `Set in a vividly realised world of elite Alphas and their `weaker' Omega twins, it holds a mirror up to our obsession with perfection' Guardian Paloma's arrival, with news of Elsewhere and the possibility of a world free of the fatal bond between twins, has given Cass and the resistance a hope worth fighting for. But they are facing a Council more powerful and ruthless than Cass could ever have imagined, willing to unleash weapons from the long-buried past to maintain their power over Alphas and Omegas alike. As the stunning Fire Sermon trilogy comes to a close, the final struggle between Zach and Cass has begun - a struggle that will jeopardize not only the future of Elsewhere but the future of the world. What started with fire may end with fire.
