In the dystopian future, mankind turned his Earth to ash. Once the radiation had dissipated, civilization began to multiply once again. The human body found its Darwinian way to ensure survival. How? Every birth resulted in twins – one, a perfect specimen, better than any humans who had come before. The other had a deformity – some obvious and grotesque, and some hidden. It is now a world of Alphas and Omegas. The perfect Alphas could reproduce (twins, always), and the Omegas were barren. And the biggest catch of them all? If one twin died, so did the other. Their mortality was inexorably tied together. Cass is an Omega psychic who wants to bring down her twin Zach and the Alpha council, before they destroy what’s left of the Omegas and of Earth. Francesca Haig‘s new novel, The Map of Bones, is the 2nd installment of this incredibly unique premise.
