Astra may have found her voice as a messenger of cosmic harmony - but is anyone listening? The final installment in this critically-acclaimed SF quartet 'for Hunger Games fans of all ages' (Library Journal). Perfect for fans of Ursula K. Le Guin, Joan Slonczewski and Joyce Carol Oates.

For ten years Astra Ordott has lived as a traitor, hated by most of her fellow prisoners and abused by the guards. She made the ultimate sacrifice to save those she loved, voluntarily giving up her freedom when she handed herself over to the Is-Land authorities. Now long-simmering conflicts are beginning to boil over again as the wider world faces devastating threats both old and new. Non-Land and Is-Land are further from reunification than ever. Outside Astra's fortified Gaian homeland, an infertility crisis is threatening the survival of the human race, while the world's reliance on rare earth metals is infuriating the ancient spirits of the planet.

Reminiscent of Ursula K. Le Guin's Always Coming Home and elements of Cloud Atlas, as well as Starhawk's The Fifth Sacred Thing . . . a believable and textured world where all is not as it seems
