In the aftermath of a failed utopia, an exiled woman fights to be reunited with her children by harnessing the mythic power that changed the planet forever. From the Sunday Times-bestselling creator of Newbury & Hobbes and author of numerous comics and novels for Star Wars, Doctor Who, and Warhammer 40,000, comes an epic modern fantasy, rich in mythology and adventure, with an emotional personal story at its heart. Twenty years ago, the World Mother awoke, forming an enormous worldbridge from manmade ruins and knotted vegetation that spanned the globe. Borders fell, millions migrated, and legendary creatures returned to the forests. But recently, the World Mother has gone silent, and the worldbridge has begun to whither. Borders are being reinstated. Now, one woman, cast out by her adoptive nation, must assemble a team of outcasts to reawaken the World Mother and bring down the wall separating her from her family.
