Set in an unsettlingly convincing near future, James Bradley’s fourth novel, Clade, opens with climate scientist Adam Leith walking along an Antarctic coastline reflecting on the state of the world and on his relationship with his partner, Ellie. After six years together, their relationship is under pressure as Ellie undergoes fertility treatment. Adam is ambivalent about bringing a child into a world that he has recently conceded to himself is ‘on a collision course with disaster’, while Ellie is fiercely determined to do so. Now, as the ground both literally and metaphorically shifts beneath Adam’s feet, he waits for Ellie to call him with the results of her latest round of treatment.
