A gorgeous, piercing memoir of two families linked through adult betrayal - and of the fierce childhood will to survive in them. When Jane Alison was a child, her family met another that seemed like its mirror: a father in the Foreign Service, a beautiful mother, and two little girls, the younger two - one of them Jane - sharing a birthday. With so much in common, the two families became almost instantly inseparable. Within months, affairs had ignited between the adults, and before long the pairs had exchanged partners - divorced, remarried, and moved on. As if in a cataclysm of nature, two families were ripped asunder, and two new ones were formed. Two pairs of girls were left in shock, a 'silent, numb shock, like a crack inside stone, not enough to split it but inside, quietly fissuring'. And Jane and her stepsister were thrown into a state of wordless combat for the love of their fathers. The sisters' contest, recounted by Jane Alison with stunning emotional insight, is waged throughout less-than-innocent childhoods - and ends in a tragedy that is at the same time unthinkable and inevitable.
