`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.
