In this dazzling piece of reportage, Anna Krien investigates the contemporary animal kingdom and our place in it. From pets to food, from wildness to science experiments, Krien also reveals how animals are faring in this new world order. Examples range from the joyful to the deeply unsettling. As Krien delves deeper, she finds that animals can trigger primal emotions in us, which we are often not willing to acknowledge. "Us and Them" is a clear-eyed look at how we do - and should - treat animals.
